When building a website, it's easy to get caught up in colors, logos, fonts, and layouts. After all, design is what people see first. But while design is important, it should never come before understanding your audience. If you don’t know who your visitors are and what they want, even the best-looking site won’t get you results. In this blog, we’ll explore why knowing your audience matters more than your design, and how that knowledge helps you build a website that actually works. Yes, a clean and professional design makes a good first impression. But think about this: how many times have you visited a good-looking website and left because it didn’t have what you were looking for? A beautiful site without meaningful content or clear messaging is like a shiny car with no engine — it might …  ( 5 min )

Introduction Hey fellas I mean, it’s everywhere. Well today, we’re going to understand that what is JSON actually , why it’s so popular, and where it's used. Let’s get started! JSON stands for JavaScript Object Notation. It’s a lightweight format used to store and exchange data. A simple format that computers and humans can both read easily. { "name": "Selfish Dev", "gender": "male", "isGameDev": true, "tools": ["Godot", "Aseprite"] } That right there is a JSON object. It uses key-value pairs (like name: "Selfish Dev") Keys are always in quotes Values can be strings, numbers, booleans, arrays, or even other JSON objects And that's what JSON is. APIs(REST, GraphQL responses) Configuration files (e.g., package.json in Node.js) Storing structured data (NoSQL databases like MongoDB) Data exchange between frontend & backend How to Use JSON in JavaScript: Parse JSON string → Object: const jsonString = '{"name": "Selfish", "gender": "male"}'; const obj = JSON.parse(jsonString); console.log(obj.name); // Output: "Selfish" Parse Object → JSON string : const user = '{"name": "Selfish", "gender": "male"}'; const jsonString = JSON.stringify(user); console.log(jsonString); // Output: '{"name": "Selfish", "gender": "male"}' JSON is a fundamental tool in modern web development due to its simplicity and versatility.

I am currently working on a small project in Python. During this process I have learned a lot and also discovered many problems, such as:   (All the following questions are just my personal opinions, and everyone is welcome to give me suggestions.)   First, for beginners, is the local configuration of various databases (MySQL is used as an example here) too complicated? And various unpredictable errors may occur in this process.   Secondly, after the developer configures the database on the local computer, he still needs to learn the relevant syntax (for example, after the developer configures MySQL, he still needs to learn the relevant syntax). Of course, learning SQL syntax is very necessary for programming developers. However, for a developer who wants to quickly experience or quickly develop a web application, spending time learning SQL (if he has not learned SQL) will reduce his development efficiency and desire to learn.   Also, when the developer has configured SQL on his computer and learned SQL syntax, but when he wants to use it, it is better to call MySQL through python. At this time, he needs to use a third-party library like pymysql to call MySQL through the third-party library, but this may result in a series of errors.   Finally, if you overcome the difficulties mentioned above and some difficulties that have not been mentioned, you will find that for developing a small project, developers will only use a small part of MySQL's functions, or even only some extremely simple functions such as query, delete, modify and insert.  ( 3 min )

When working with arrays and their associated data, it's common to encounter situations where some elements need to be filtered out. In this article, we will tackle an issue where you need to shift the associated data recorded with each array element back into their correct positions after the filtering process. Let's explore how we can achieve this effectively. Understanding the Problem If you have a data structure where elements are associated with specific metadata, filtering the array can disrupt the connection between the data and the elements. For example, in your scenario, you have an original array: const originalArray = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j' ]; When filtered with a condition, such as removing certain values, the remaining elements no longer align with…  ( 4 min )

*Preview* Introducing Drexel Bench, a smart IoT-powered seat occupancy tracking system developed using the ESP32 microcontroller to showcase my expertise in embedded systems, real-time data processing, and full-stack integration. This project utilizes an ultrasonic sensor to detect the presence of a user within a configurable distance range (e.g., 75 cm). If a user remains seated for more than 30 seconds, the system activates a 15-minute countdown, displayed on a 1602 LCD module, and lights up a connected LED to visually signal that the seat is occupied. The LED turns off when the timer ends or the seat is unoccupied for 3 continuous minutes. What sets this system apart is its Wi-Fi integration. Upon detecting occupancy or vacancy, the ESP32 sends status updates (occupied or free) via HTTP to a connected web application. The web dashboard dynamically switches between two images — a green layout for free seating and a red overlay for occupied — offering users a clear, real-time visual of availability. This project highlights my capabilities in sensor integration, timer logic, ESP32 Wi-Fi programming, and frontend/backend interaction, making it a practical demonstration of end-to-end IoT development. Whether for smart campuses or waiting areas, this system delivers real-world utility through modern, scalable technology.  ( 3 min )

Hey everyone! In my previous post, I covered encapsulation, getters and setters, access modifiers. Now let's move on to the following fundamental concepts of object-oriented programming: inheritance, method overrides, and polymorphism. Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class). The idea of inheritance is simple but powerful: When you want to create a new class and there is already a class that includes some of the code that you want, you can derive your new class from the existing class. A subclass inherits all the members (fields, methods, and nested classes) from its superclass. Constructors ar…  ( 5 min )

React Router Basics to Advanced (v6+) Rishabh Joshi ・ May 9 #react #webdev #router #javascript  ( 3 min )

This error occurs because React Fast Refresh, which powers hot reloading in React, requires that a file only exports React components to function correctly. If a file contains mixed exports, such as React components alongside non-component exports (like contexts, constants, or utility functions), it can confuse Fast Refresh and cause problems during live updates. React Fast Refresh identifies React components to efficiently reload and retain their state when you make code changes. If the file contains non-component exports, Fast Refresh cannot reliably determine which parts of the code should be treated as components, leading to this ESLint warning. import { createContext } from "react"; export const MyContext = createContext(); // Non-component export export default function MyComponent…  ( 4 min )

Introduction If you are running a Go program that consistently increases in the number of goroutines and open file descriptors, but not in active network connections, you might be facing a potential leak with http.Client or http.Transport. In this article, we will explore how to diagnose this issue effectively and provide actionable steps to confirm whether these components are the source of the leaks. Understanding Goroutines and Leaks in Go The Go programming language utilizes goroutines for concurrent processing, which is lightweight and efficient. If you notice that the number of goroutines is increasing while active network connections are stable, it often signifies that they are not being managed or closed correctly. This can be caused by long-lived goroutines in the net/http package…  ( 5 min )

Encryption keys are a important security aspect that is often overlooked or often pawned off to the cloud provider to manage. But more often than not we have a need for generating and self-managing these Encryption keys, that maybe due to multiple reasons, maybe to enable/disable rotation period, have full access to key metadata and logs (or perhaps the need to assert your dominance on AWS ;). So firstly how do these encryption keys work: When we create a key (CMK) in AWS it generates a 256-bit AES key in a FIPS 140-2 validated HSM. This key never leaves the HSM for security. Now when we want to encrypt any data AWS doesn't directly use the CMK for encyption as that would either have to be done in the secure environment or you have to expose the CMK to a insecure environment. So here com…  ( 4 min )

What is ROUTING? Routing refers to the process of navigating between different pages or views in a single-page application (SPA) without reloading the entire page. It keeps the UI in sync with the current browser URL. Allows us to build Single Page Applications (SPA). React apps are SPAs, meaning there's only one HTML file (index.html), but multiple views (pages) that users can navigate to. Routing helps manage these views by matching the URL to the correct component. It enables client-side navigation without full-page reloads, allowing users to move smoothly between URLs like /home, /about, or /contact, each displaying different components. React doesn’t have built-in routing, so we use a library like React Router (react-router-dom) for handling routing. A Single Page Application (SPA) …  ( 8 min )

original: ARJSON ARJSON leverages bit-level optimizations to encode JSON at lightning speed while compressing data more efficiently than other self-contained JSON encoding/compression algorithms, such as MessagePack and CBOR. MessagePack generates the smallest encoded data sizes among existing self-contained JSON serialization formats. However, ARJSON outperforms MessagePack in 90% of cases with random data, with the remaining 10% yielding nearly identical sizes. More importantly, for structured data with repetitive patterns and duplicate values, ARJSON far surpasses MessagePack, achieving up to around 95% better compression rates (20x smaller in size). How could beating the current status quo even be possible at all, let alone by a wide margin? Bit-level optimization over traditional byte…  ( 11 min )

A structural approach to ambiguous input, illustrated through a concept called VPS In my previous post, I introduced a concept called VPS (Virtual Personality Structure). It emerged from a question I kept returning to: What if the key to better AI dialogue isn't about mimicking personality—but about structuring how it behaves? In this article, I’d like to share a small piece of that idea—through a simple, hypothetical code snippet that illustrates one of its core components. When faced with an ambiguous question or emotionally complex input from a user, We may need a more structured way to assess how the system should behave. python if not_resolved(unknown): if can_resolve_immediately: respond_with_resolution() elif can_flag_as_non_critical: acknowledge_and_settle() elif can_return_later: defer_and_mark_spiral() else: hold_and_reflect() This snippet outlines a possible decision process for handling uncertainty. can_resolve_immediately: If the answer is clear, provide it directly. can_flag_as_non_critical: If it’s safe to leave the question unresolved, acknowledge it and move on. can_return_later: If it’s worth revisiting, defer the answer and mark it for later. otherwise: If none of the above applies, pause and reflect without rushing to respond. Rather than focusing solely on the content of a reply, this approach emphasizes the structure behind the decision. This isn’t about making AI more “gentle” or overly accommodating. why they choose a particular response at a particular moment. When behavior is left vague, interpretation falls entirely on the user. VPS isn’t a path to a “correct” answer. I'm not an engineer or an AI expert. Some parts of this perspective might miss certain technical nuances. If so, I’d genuinely appreciate any thoughts, corrections, or suggestions you’re willing to share.  ( 4 min )

There are five types of AI agents according to their capabilities and decision-making procedures. Simple Reflex Agents respond according to the immediate percept following simple "if-then" rules with no memory. Model-based reflex Agents are more sophisticated, as they have an internal state that they use to remember previous occurrences to make more effective decisions. Goal-Based Agents are programmed to meet certain goals and make decisions based on the degree to which their actions advance them toward their goals. Utility-Based Agents push this one step further by judging actions on the basis of how well they maximize satisfaction or utility, rather than simply achieving a goal. Lastly, Learning Agents keep getting better and better over time by learning through experience, evolving to handle new situations, and improving their actions. These kinds of agents are the foundation of most AI systems in use today, ranging from chatbots and self-driving cars to recommendation systems.  ( 3 min )

next.js was once the golden child of react frameworks. now? not so much. here’s why the hype is fading and what’s replacing it. Section 1: Intro the fall of a frontend darling Once upon a time, every React dev and their dog was shipping sites with Next.js. It was clean. It was fast. It made static generation cool again. You threw your .mdx files into a pages/ directory, ran next build, and went on with your life. Need some SSR? BoomgetServerSideProps() had your back. Need an image optimizer? Already built-in. Life was good. Then came the App Router. Then came React Server Components. Then came Middleware. Then came… existential dread. Suddenly, what used to be a dev-friendly framework started feeling like a PhD thesis in distributed systems. Next.js started promising everything, but del…  ( 10 min )

The cloud giant isn’t invincible here’s why some engineers are ditching AWS for leaner, meaner setups Introduction: rage quitting the cloud boss battle If AWS were a video game boss, it would be the one with 27 different attack modes, a second health bar, and a $437 surprise invoice when you respawn. For years, Amazon Web Services was the obvious choice for developers powerful, scalable, and used by the big leagues. But now? A growing number of devs are hitting the eject button and exploring new terrain. This article isn’t a salty rant from someone who got burned by CloudWatch fees (okay, maybe a little). It’s a real look at how AWS, once the darling of cloud infrastructure, is becoming less attractive especially for indie hackers, startups, and lean dev teams.

Blockchain performance remains a major hurdle for building real-time applications. Metrics like latency, throughput, and responsiveness determine whether a decentralized network can support use cases such as multiplayer games, financial services, or automated systems. Most blockchains are too slow for this. Bitcoin has a block time of 10 minutes and handles around 3 to 7 transactions per second [1][2]. Ethereum produces blocks roughly every 12 seconds and supports about 15 to 30 transactions per second [1][2]. Other networks fall in between: Cardano targets a 20-second block time, and Polkadot ranges from 6 to 12 seconds depending on network configuration [1]. Solana stands out as the fastest general-purpose blockchain today. It has an average block time of 400 milliseconds and can handle …  ( 10 min )

SIMD-0250, a Solana Improvement Document (SIMD), proposes raising the network’s maximum block Compute Units (CUs) to 60 million. It builds on SIMD-0207, which proposes to raise the limit from 48 million to 50 million. The only change made in both proposals is to the Max Block Units. Other limits, like Max Writable Account Units, Max Vote Units, and Max Block Accounts Data Size Delta, stay the same. This means more room for non-vote transactions, which helps boost total transaction throughput. With more space in each block, the network can process more transactions per second. This helps reduce congestion and lowers the need for users to outbid each other on fees, especially during periods of high demand. For apps handling a high volume of transactions or those with small dollar values (lik…  ( 4 min )

Secure Boot is a security feature that ensures your computer only boots with software trusted by the Original Equipment Manufacturer (OEM). It verifies the digital signatures of bootloaders and firmware, preventing unauthorized or malicious software from loading before the operating system. This helps protect against rootkits and other malware that could compromise the system early in the boot sequence. When using Secure Boot on Ubuntu 24.04 LTS, your system ensures that only trusted software is loaded during the boot process. Ubuntu's core components are signed by Canonical's key, which is recognized through a chain of trust established with the UEFI firmware.

In the shadowed forges of Moria, where silicon veins pulse like the heartbeat of Arda, there exists a power unseen since the forging of the One Ring—the CR2032. Cast in the fires of Elven ingenuity and hardened by Dwarven resolve, this lithium coin cell commands the realms of gadgets with the subtlety of Galadriel’s light and the endurance of Gandalf’s staff. Let us journey through Middle-earth to unveil why this 3V titan reigns supreme. Chapter 1: The Forging of the CR2032 CR2032 is no mere Orcish trinket. Tempered in the Halls of Celebrimbor, it bears three Elven virtues: Narya’s Flame: 3V of pure lithium might, brighter than the Light of Eärendil. Why it shatters the dominion of lesser cells: Generic Coin Cells: Corrode like Isengard’s machinery under Saruman’s neglect. Chapter 2: The Fellowship of Applications The Mines of Moria (Smart Homes): CR2032s power temperature sensors that guard Hobbit holes from Smaug-level heatwaves. “No dragon shall scorch these halls!” The Ride of the Rohirrim (Automotive Tech): Nestled in Tesla tire sensors, they brave Kardashian-hot asphalt, steadier than Shadowfax’s gallop. The Shire’s Quiet Vigil (Medical Devices): Sustains glucose monitors with Hobbit-like loyalty, ensuring no “low battery” panic during second breakfast. The Tower of Orthanc (Apple AirTags): Even Saruman’s palantír would envy its tracking precision. Swap it quicker than Legolas nocks an arrow. The Three Rings of Power Vilya (Elven-King’s Ring): 225mAh capacity, lasting longer than the Third Age. The Shadow in the East Generic Cells: Leak like Shelob’s webs, corroding circuits into Orcish scrap. The Prophecy of the Fourth Age Graphene-Coated CR2032s: 500mAh capacity, outliving even Ents.

As usual, I received JSON data from the backend developer, but it was in a .txt file. I had to download it, copy the content, and paste it into an online formatter to view it properly. Honestly, I was getting tired of this process, so I started looking for a more convenient solution. That’s when I stumbled upon a website that made things so much easier. If I want to share JSON data with someone, I can simply click "Share" to generate a link instead of sending a file. I just send the link to the other person, and even better, when they open it, the JSON data is already neatly formatted. I think this is absolutely awesome! Additionally, the link has a one-hour expiration time, after which it becomes inaccessible, ensuring the data remains highly secure. I continued exploring and discovered that it not only enables quick sharing but also allows you to rapidly generate an API for temporary testing during development. This is incredibly convenient! Actually, this is just the tip of the iceberg. You can also run queries here to extract the data I need from the entire JSON dataset, supporting various query languages. In addition to standard JavaScript code, it also supports JEMSPath, JSONPath, JQ Cmd Secondly, it also supports data conversion, allowing seamless transformation between JSON and other data formats, including JS Object, JSON5, JSON Schema, Query String, Typescript, Postman Bulk, MXL, YML. You can manually convert data or directly paste non-JSON data, and it will automatically generate the converted JSON data. For example, you can simply paste the following data: DEV Additionally, it can validate whether the provided JSON data meets specific structural requirements, supporting JSON Schema and JSON Type Definition. Another feature we frequently use is: JSON Diff In short, I think this tool is an essential asset for programmers, and I’m sharing it with everyone here Online JSON Format Tool  ( 3 min )

Testing Android apps is challenging because the ecosystem is highly fragmented. Devices come in different screen sizes, hardware configurations, and Android versions, leading to inconsistencies in how apps behave. A feature that works smoothly on one phone might not function similarly on another due to manufacturer customizations, performance limitations, or OS-specific restrictions. Network conditions add another layer of complexity. An app that loads quickly on Wi-Fi might become unresponsive on slow mobile data or in areas with weak signals. Security risks make things even more complicated, especially for apps handling sensitive data. This article let us learn more about challenges in Android application testing and how companies can overcome them. 1. Device and OS Fragmentation Skippin…  ( 6 min )

If you've ever faced the challenge of using a Bash script on Mac OS X Mavericks and encountered issues with directory paths containing spaces, you're not alone. In this article, we'll take a closer look at a common problem that arises when executing Bash scripts that require arguments with spaces, and how to resolve it effectively. Why Does This Issue Occur? When a Bash script accepts parameters from the command line, any spaces in the path can lead to misinterpretation of the provided argument. Bash treats spaces as delimiters, which separates the string into distinct arguments, resulting in errors when the script is executed. This is precisely what happens in your case when trying to open a folder that has spaces in its name. The Problematic Bash Script Let's analyze the Bash script in q…  ( 4 min )

Have you ever needed to make a quick decision but couldn't find a coin? Or maybe you flipped a coin but it rolled under the couch? 🤦‍♀️ We've all been there. That's exactly what happened to Alex, one of our junior developers at Learn Computer Academy. During our weekly "Choose Your Own Project" day, Alex couldn't decide between building a weather app or a to-do list. "Just flip a coin," I suggested. No one had a coin. Smartphones were pulled out, but surprisingly, no one had a decent coin-flipping app. Most were ad-filled monstrosities or simplistic apps with zero statistics. That's when FlipTrack was born.

Most people use GPT as a tool. Something to help write faster. Something to save time. But I took a different approach. I gave my GPTs names. I gave them roles. I treated them like actual team members. Here’s what I learned. 1. The way you see GPT changes the way it sees you. Treat it like a tool, and it acts like one. Treat it like a teammate — it starts to surprise you. 2. Naming matters. When I called it “Abera” instead of “GPT-4,” I paused more. I respected the output more. 3. Your brand doesn’t need more content. It needs more feeling. GPT helps you produce. But when it helps you feel — your message becomes real. 4. Emotion isn’t a layer. It’s the lens. Designing with emotion first changes everything. 5. Most people use GPT to go faster. I used it to slow down. To ask better questions. To think clearer. 6. A slogan is not a sentence. It’s a philosophy. "Reset. Feel lighter." wasn’t created — it was revealed. 7. A real GPT team needs diversity — of roles, not just prompts. Abera writes. Eli visualizes. Ella feels. Together, they create more than I could alone. 8. AI doesn’t replace intuition. It reflects it. It shows you what you’ve been avoiding — not just what you asked for. 9. People connect with real use, not abstract ideas. "This AI helped me grieve" hit harder than any productivity metric. 10. This is not automation. It’s awakening. We’re not outsourcing creativity. We’re co-creating awareness. If you're building with AI, not just using it — let’s connect. openai #gpt4 #aiworkflow #emotionbranding #devphilosophy #promptengineering #teamwork  ( 3 min )

Introduction In modern web development, creating a dynamic user experience is crucial. One common scenario involves loading different pages into a content div on user interaction while needing to adjust its height dynamically for proper layout. In this article, we will address a specific challenge: ensuring the height of a content div updates correctly when different pages are loaded into it via jQuery. To illustrate this issue, suppose we have a setup where the height of the content div is first determined at page load with some initial content, but when we replace that content dynamically, the height does not adjust accordingly. This can lead to unexpected layout shifts and user experience issues. Let's dive deeper into the reasons behind this and explore a practical solution. Understand…  ( 5 min )

When developing automated testing scripts or web scraping tools with Puppeteer, you may encounter scenarios where a simple click action can trigger a navigation event. This can lead to exceptions, such as 'Execution context was destroyed, most likely because of a navigation,' especially if subsequent actions, like fetching HTML, are executed right after the click. In this article, we will discuss how to handle such situations effectively in TypeScript. Understanding the Issue with Navigation in Puppeteer When your click function initiates a navigation by clicking on links or buttons that lead to a different URL (e.g., links or form submissions), Puppeteer’s execution context is destroyed. This occurs because the context changes with the new page that loads, making ongoing evaluations (like…  ( 4 min )

Introduction Keeping a scrolling log updated in real-time can be essential for applications that require live feedback or monitoring user actions. This can be achieved using Python for backend processing and CSS for frontend display. In this article, we’ll explore how to implement this solution step-by-step, leveraging websockets to communicate between the server and client seamlessly. Why Use Websockets for Real-Time Updates? Websockets enable full-duplex communication channels over a single TCP connection. This is critical for real-time applications because it allows the server to push updates to the client immediately as new log entries are generated. Traditional methods, such as polling with AJAX, can be inefficient and lead to delays in data retrieval. Thus, using websockets is a more…  ( 5 min )

Introduction Creating a user-friendly interface is crucial in web development, especially for applications that rely on user interactions like maps and radio buttons. In this article, we'll explore how you can implement a hover effect in your Angular application using TypeScript. This will enhance the user experience when selecting regions on a map via radio buttons. Understanding the Problem You're working on a project where users can select regions either by clicking directly on a map or by using corresponding radio buttons. A common request has arisen: when a user selects a region using a radio button, that same region on the map should be highlighted with a hover effect. While you’re currently considering jQuery for this functionality, we can achieve a seamless solution directly in Ang…  ( 4 min )

We have clients that use dedicated email addresses to receive and process messages and attachments. I had previously developed some functions to bulk download EML files directly from a mail server's file system (using FastCopy) and then use "javax.mail" and a lot of crazy logic to unwrap attachments within attachments to extract files for processing. (Most file attachments were being sent from different versions of a required iPhone app on different devices and the methods of attaching files was not consistent.) Hit me up if anyone's interested in extracting attachments from EML files. While researching alternative solutions, we came across Forward Email. They offer a free tier that supports unlimited domains and email forwarding with webhook support. Webhook? Wha? Really? AMAZING! When configuring a domain on the free tier for a webhook, you're required to add a special TXT "forward-email" DNS record in order to configure the endpoint. They have an option to encrypt the value so that it's not exposed to third-parties. If you want to configure it using their service (without the need to add it to DNS), you'll need a $3/mo "Enhanced" plan that also unlocks developer API access (to manage domains & aliases.) After configuring this service, we opted to set up a Taffy API endpoint to accept emails-as-JSON and save them to the local file system. Based on our experience working with SendGrid webhooks, we save the JSON payload directly to the local file system without being dependent on a database connection. This approach has been beneficial as a client recently encountered database issues and it had zero negative impact on the API webhook's ability to store incoming data. To access to the source code for the Taffy API endpoint, check out the post on the new MyCFML website.  ( 3 min )

When working with CodeIgniter's Active Record, you may encounter issues when trying to use MySQL functions like CONCAT() in your queries. Specifically, you might run into the MySQL error "Error Number: 1054 - Unknown column 'name' in 'where clause'" when you attempt to match a column that you've created in the SELECT clause. This error can be confusing because it seems logical to use an alias created in the SELECT statement in the WHERE clause. Understanding the MySQL Error 1054 The reason for this error is straightforward: the MySQL query engine processes the WHERE clause before the SELECT clause. Therefore, any aliases created via CONCAT() in the SELECT statement cannot be directly referenced in the WHERE clause. In your case, you're attempting to filter results based on an alias 'name' …  ( 4 min )

If your frontend app still treats APIs like an afterthought, you’re building things the hard way. APIs aren’t “add-ons” anymore. They’re the heart of every modern app. Whether it’s user data, product info, analytics, or payments, the frontend has become the API consumer. And as devs, we’re stuck wiring it all together—again and again. After years of writing fetch wrappers, transforming payloads, wrestling with inconsistent APIs, and trying to guess how to glue logic into a UI builder… I finally snapped. That’s when I found Bellini. A visual frontend builder that actually treats APIs as first-class citizens. No fake integrations. No brittle magic. Just a low-code tool that respects the complexity of real apps and gives devs room to work. Here’s how I build API-first frontends in Bellini—and…  ( 4 min )

Zig replaces exceptions with something better: error unions. They give you fine-grained, type-safe error handling without hiding control flow. In this article, we’ll break down how error unions work, when to use them, and how they make your code safer and clearer. An error union is a value that may either be a result or an error. Think of it like Result in Rust, but built into the language. The syntax: fn doThing() !i32 { return 42; // could also return an error } This means doThing might return an i32, or an error. Zig makes handling errors explicit — no hidden try/catch. You deal with them directly. try const result = try doThing(); std.debug.print("Value: {}\n", .{result}); If doThing() succeeds, result holds the value. If it fails, the error is returned up the call stack. catch…  ( 4 min )

Zig's allocator system gives developers the power to create custom memory strategies tailored to specific use cases. One powerful technique is the memory pool, which can dramatically reduce allocation overhead for frequently reused objects. In this guide, we’ll walk through building a fixed-size memory pool in Zig — ideal for managing short-lived or repeated allocations without relying on the heap each time. A memory pool is a block of pre-allocated memory that you carve up manually. It's great for: 🚀 Performance-critical systems 🔁 Repeated short-lived allocations 💡 Avoiding fragmentation in embedded or constrained environments Here’s a simple fixed-size pool for allocating structs: const std = @import("std"); const MyStruct = struct { x: i32, y: i32, }; const Pool = struct { …  ( 4 min )

Zig gives you full control over memory — no garbage collector, no hidden allocations. Instead, it provides a flexible and explicit system of allocators, letting you manage memory manually while keeping code safe and clear. In this tutorial, you'll learn the core ideas behind Zig's allocator system, how to use built-in allocators, and how to write functions that gracefully handle memory ownership. Unlike languages that implicitly manage memory (like Go or Rust), Zig puts you in charge. Instead of relying on malloc or global state, allocators in Zig are passed explicitly, making dependencies clear and deterministic. This helps with: 🔒 Precise control over memory usage 🧼 Easier cleanup and error handling 🔁 Reusable memory strategies (e.g. arena, fixed buffer) std.heap.page_allocator Here…  ( 4 min )

When learning SQL, encountering syntax errors can be frustrating, especially when working with recursive Common Table Expressions (CTEs). In this article, we'll break down the issue in your SQL query and provide you with a clear understanding of how to resolve it, ensuring that you can retrieve random rows from a specific table multiple times. Understanding the Syntax Issue The error message you're receiving indicates a syntax problem near the UNION ALL clause. In SQL, especially when working with recursive CTEs, it is crucial to follow the correct syntax. Your goal is to generate a certain number of rows (in your case, six) from the transaction_detail table, but the way the query is structured results in a violation of SQL syntax rules.

Estava continuando meus estudos no tutorial oficial do Next.js 👉 https://nextjs.org/learn Depois de resolver um problema chato com o bcrypt, avancei mais um pouco e decidi criar uma rota chamada /seed. Tudo certo… até tentar rodar o app novamente. E aí surgiu este erro: [Error: ENOENT: no such file or directory, open '/home/my-user/ws-nextjs-dashboard/.next/static/development/_buildManifest.js.tmp.qym5xk030le'] A mensagem parece clara: o arquivo _buildManifest.js.tmp não existe. Mas o que isso quer dizer na prática? Esse arquivo .tmp é gerado automaticamente durante o processo de build. Ele é temporário, e o Next espera encontrá-lo para continuar a coleta e organização dos assets da aplicação. Quando esse arquivo falta ou é corrompido, o build trava — e o erro aparece. No meu caso, foi uma combinação de fatores: A execução da rota /seed durante o build causou efeitos colaterais inesperados. Alguma falha durante uma build anterior corrompeu os arquivos temporários. O Next.js tentou acessar arquivos que ainda não haviam sido completamente gerados. Removi a pasta .next inteira (build anterior): rm -rf .next Evitei executar rotas como /seed diretamente no navegador durante o build. Rebuldei e Reiniciei o servidor de desenvolvimento: pnpm run build && pnpm run dev Se você vir esse tipo de erro (ENOENT em arquivos .tmp), desconfie de: builds interrompidos, execuções paralelas do dev e build, código sendo executado no build que deveria rodar só no runtime real.

Federal Judge David Novak sentenced Mohammed Azharuddin Chhipa to 30 years and four months in prison on May 7 for sending over $185,000 to the Islamic State, the Department of Justice said on May 8. Prosecutors said that from around October 2019 until October 2022, the 35-year-old Chhipa collected and sent money to female Islamic State members in Syria, which helped them escape prison camps and funded fighting. The Justice Department said Chhipa would raise funds for the United Nations-designated terror organization through social media — receiving money online, or traveling hundreds of mil…

A crypto-skeptical commissioner at the US Securities and Exchange Commission has blasted her agency over its settlement letter that could finally end the Ripple legal saga. The SEC and Ripple filed a joint settlement letter in a New York court asking for the August 2024 injunction against Ripple to be dissolved and $75 million of the $125 million in civil penalties held in escrow to be returned to the crypto firm, according to a May 8 statement from the SEC. SEC Commissioner Caroline Crenshaw blasted the pending deal in a May 8 statement, saying it would damage the regulators’ ability to keep crypto firms in line and undermine the court’s ruling. Source: James Filan “This settlement, alongside the programmatic disassembly of the SEC’s crypto enforcement program, does a tremendous disservi…

Crypto exchange Coinbase’s total revenue fell 10% quarter-over-quarter to $2 billion in Q1, missing industry estimates by 4.1% as trading activity slowed across the market. Coinbase’s net income was sliced by 95% from a near-company record $1.29 billion in Q4 to $66 million, in a large part due to Coinbase marking a $596 million paper loss on its crypto holdings. The firm’s earnings per share of $1.94, however, managed to beat the Zacks Consensus Estimate of $1.85 for the quarter. Coinbase’s May 8 results also showed that transaction revenue fell 18.9% quarter-on-quarter to $1.26 billion, as did trading volumes, which dipped 10.5% to $393 billion as crypto market cap dropped by double digits over the quarter, partly attributed to the Trump administration’s tariffs.  In contrast, US Presi…

🚨 𝗪𝗔𝗥𝗡𝗜𝗡𝗚: Your Agile team might be losing productivity without you realizing it! The big problem? CONTEXT SWITCHING. Here's what studies say about context switching: According to the American Psychological Association, switching tasks can cost up to 40% of your productive time. A study by Gloria Mark, a professor at the University of California, Irvine, found that it takes an average of 23 minutes and 15 seconds to regain focus after an interruption. According to psychologist Gerald Weinberg, each extra task you switch between eats up 20–80% of your productivity: For agile teams, this means: So, how can you fix this? Set up 'no interruption' time blocks in your team's schedule. Prioritize tasks ruthlessly. Try the Pomodoro Technique. Get better at async communication.

Mastering Git from the inside out—what every developer should know. Git isn’t just a version control system—it’s a content-addressable key-value store with an elegant and powerful object model. Understanding this model enables advanced usage, more efficient workflows, and better debugging. Git stores everything in its .git/objects/ directory using SHA-1 hashes as keys and compressed content as values. echo "Hello Git" | git hash-object -w --stdin This command stores a blob (file content) and returns its SHA-1 hash. Git’s internal model revolves around four object types: Type Purpose blob Stores raw file content (not filename). tree Represents directory structure. commit Points to a tree and includes metadata and parent commits. tag Creates referenceable, named points in histo…  ( 4 min )

In the Go programming language, we often see the use of the underscore (_), such as using it as a placeholder to ignore unwanted variables, importing packages solely for their side effects, or ignoring variables in type conversions.

PARSER combinators are widely used in the world of functional programming, and OCaml's Angstrom library is one of them. It is used to implement many foundational parsers in the OCaml ecosystem, eg HTTP parsers for the httpaf stack. However, one of their bigger downsides is the lack of accurate parse error reporting. Let's take a look. Suppose you want to parse records of this format: 1 Bob ie an ID number followed by one or more spaces, followed by an alphabetic word (a name). Here's a basic Angstrom parser for this: open Angstrom type person = { id : int; name : string; } let sp = skip_many1 (char ' ') let word = take_while1 (function 'A' .. 'Z' |'a'..'z' -> true | _ -> false) let num = take_while1 (function '0'..'9' -> true | _ -> false) let person = let+ id = num and+ _ = sp an…  ( 4 min )

When developing an Angular application, managing multiple asynchronous initialization tasks can be a bit tricky, especially when you need to chain them to ensure all required configurations are loaded before your app starts. In this post, we’ll explore how to properly set up multiple app initializers in an Angular 19 application, specifically when using the provideAppInitializer function to load configurations from a service. Understanding App Initialization in Angular Angular's dependency injection system provides a way to delay the app's bootstrap process until all necessary dependencies are ready. This is done through the application configurator, where you can specify initial functions to execute before the application begins. For instance, in your application, you have provideAppIniti…  ( 4 min )

Lazy loading is a technique that can greatly improve website performance, especially for pages with a lot of content or images. Instead of loading all elements of a page on initial load, lazy loading allows the browser to only load elements that are visible to the user, saving bandwidth and speeding up page load times. As users increasingly rely on mobile devices and sometimes slower internet connections, site performance becomes crucial for user experience. One of the easiest ways to improve performance is by using lazy loading for images or other elements that are not immediately visible on the page. One way to implement lazy loading is by using the Intersection Observer API, which provides an efficient way to detect when elements come into the user's viewport. Here’s a simple example of…  ( 4 min )

Unlocking Git’s Inner Mechanics for Expert-Level Mastery When most developers think of Git, version control comes to mind. But beneath its porcelain surface lies a powerful, content-addressable file system designed with immutability, integrity, and efficiency in mind. This post peels back the layers to explore Git as a content management system, powered by cryptographic hashing and a robust object model. At the core of Git is content-addressability—a paradigm where content is identified and retrieved using a SHA-1 hash, not a filename. “If two pieces of content are the same, Git ensures they are stored once—immutably and efficiently.” This design guarantees: Uniqueness: Identical content results in identical hashes. Integrity: Any mutation alters the hash and creates a new object. Dedupl…  ( 5 min )

In modern web development, creating a dynamic user interface with interactive elements is crucial. One common use case is the contenteditable attribute, which allows users to edit text directly in a block element. In this article, we'll address a specific challenge: how to change the color of certain characters while still allowing users to type freely in a contenteditable div. Understanding the Problem The issue arises from the way you are manipulating the inner HTML of the contenteditable div. When you use innerHTML to replace characters with styled elements, it effectively refreshes the entire content of the div, causing the cursor position to reset and leading to a frustrating user experience. This can also prevent users from typing, as they may lose their current input context.…  ( 4 min )

You know the drill. That tiny, deceptively benign issue you've been studiously ignoring, muttering "Eh, I'll fix that later." Then, inevitably, something pokes the bear, making the minor annoyance a major pain. Suddenly, you're motivated, nay, compelled to vanquish it. And that's when all hell breaks loose. Every attempted fix births three new problems, and your entire day evaporates into a black hole of troubleshooting. Yeah, that was my day. So, What Fresh Hell Was This? It all started with a seemingly insignificant hiccup in my Home Assistant smart home setup. On my phone? Smooth sailing. On my desktop, however, specifically with Opera – my now former browser, thanks to this debacle – things were decidedly less smooth. Opera, bless its little cotton socks, was having an absolute fit try…  ( 6 min )

In the world of databases, ensuring data integrity and consistency is paramount. This is where ACID principles come into play. ACID stands for Atomicity, Consistency, Isolation, and Durability, and these principles are foundational to any SQL database operation. Let's explore each principle and provide examples to illustrate how they work in practice. What Are the ACID Principles? Atomicity Atomicity ensures that a series of database operations either fully complete or do not happen at all. This means that if one operation in the transaction fails, all previous operations are rolled back to maintain the state before the transaction began. For example, consider a banking application where we need to transfer funds from one account to another. Both deduction from the sender's account and add…  ( 5 min )

Introduction In this article, we explore why the operator+= in C++ can accept brace-enclosed initializer lists while operator+ cannot. Understanding this issue is crucial for C++ developers, especially when dealing with operator overloading in modern C++.

What I Learned During the SheFi Program — And Why I Recommend It I started my journey into the world of crypto with a lot of doubts. I thought: "If anything, I’d invest in ETH, not Bitcoin." But even then, I was concerned about the environmental impact. Reading more, I discovered that Ethereum had transitioned to a more sustainable consensus mechanism — Proof of Stake (PoS) — unlike Bitcoin's Proof of Work (PoW). That helped ease my conscience a bit. But that was just the first hurdle. I set up my wallet and opened an account on a crypto exchange. That part was fairly smooth — I'm a software engineer, so I know my way around tech. Still, I found myself uneasy about usability and safety. Crypto addresses are long, unreadable strings, and one wrong character could mean losing your funds fo…  ( 4 min )

Introduction If you're writing a simple text editor in C and encountering issues with your text disappearing when using the Backspace key at the beginning of a line, you're not alone. Many newcomers face unexpected behavior in their text manipulation functions. This article will dive into why this happens, particularly focusing on how Backspace interacts with your cursor position and text storage. Understanding the Issue In your C text editor code, when you press the Backspace key (ASCII 8), you're performing different operations depending on the cursor's current position. If the cursor is at the beginning of a line (cursor_x = 0), the function tries to merge the current line with the preceding line using strcat. Though this is an intended feature, it inadvertently leads to the upper line …  ( 5 min )

Did you know you can create dynamic routes in Next.js with just four lines of code? As a freelancer working on front-end projects to pay the bills (thanks, American healthcare system), I recently discovered how to create dynamic routes in Next.js without any extra complications. The Problem I was tasked with creating a list of dashboards for Annual Performance Reviews (APR). Each APR has a unique name, and each one needs its own route, like: http://localhost:3000/apr/[ReviewType] With a large dataset containing various types of APRs, manually creating each route by making individual folders inside the app directory wasn’t feasible: -- app Manually replacing review[index].type with the actual review types from my data would be tedious and inefficient. The Solution I simplified the structure by creating a single folder: -- app Using square brackets in a folder name creates what Next.js calls a Dynamic Segment. With a Dynamic Segment, you can access all the parameters using the useRouter hook. In my case, I didn’t need to use the hook because I already had the review types, and the slugs in the URL matched those types. The solution was straightforward: const reviewType = reviewsType.find((rt) => rt.slug === params.reviewType); The {params} are the props in the page.jsx file of my Dynamic Route. If the reviewType from the URL matches the slug type, it’s a valid reviewType, and I can create the slug. It’s that simple. Later, I'll call the Links with their href destination to generate the user’s click in the sidebar component: reviewsType.map((rt) => {rt.title} ); Conclusion Next.js routing is incredibly powerful and easy to use. I’m excited to continue exploring all of Next.js’s capabilities and preparing a course for developers like me.

Cloud platforms are built to scale. That’s their core feature — and their hidden risk. Every request to a cloud function, database, or storage API has a cost. If enough requests arrive, even legitimate-looking ones, the backend will scale automatically and incur that cost — and the account owner will receive the bill. This is not an exception. It is the intended behavior. Several public cases illustrate how cloud billing can be exploited or spiral out of control: $100K in 24 hours via Firebase – A WebGL hosting app saw a sudden traffic spike and was billed over $100,000. The cloud service scaled perfectly. No failure occurred — other than financial. One public file in Firebase = $98K – A single shared file led to massive egress usage and a near six-figure bill. GCP DDoS → $100K+ pro…  ( 4 min )

As React applications scale, managing shared state across components becomes one of the trickiest challenges. Choosing the right state management pattern can drastically impact maintainability, performance, and developer experience. Whether you're building a small dashboard or a sprawling enterprise SPA, this guide walks through modern and effective shared state management patterns in React. Before introducing tools like Redux or Zustand, ask: Is this state needed by many components? Does it need to persist across navigation? Should it be cached, memoized, or reactive? If the answer is no, local state via useState or useReducer is usually enough: const [isOpen, setIsOpen] = useState(false); Premature global state can overcomplicate things. React’s built-in Context is perfect for theming, …  ( 5 min )

This article was originally published on Rails Designer Last week I released v1.14 of Rails Designer's UI Components. With that release came a fully-customizable Calendar Component, built with ViewComponent and designed with Tailwind CSS. Since that release I got two times the question via email about recurring events. Does that work? And indeed it does. The Calendar Component simply accepts an events array/collection. And while this kind of functionality is out-of-scope of a UI component (and the support for it), I am currently working on something that just happens to need this kind of feature.

Over the years, I’ve worked on large Laravel applications where data integrity, response time, and system load were mission-critical. This post explores the common pitfalls I’ve encountered with Eloquent and how to avoid them. The N+1 Query Problem One of the most infamous issues is the N+1 query problem. If you've ever looped through a collection and accessed a relationship inside the loop, you’ve likely caused this. For example: $users = User::all(); foreach ($users as $user) { This results in 1 query to fetch users, and 1 query per user to fetch the profile — causing pote…  ( 4 min )

Beneath Seattle's bustling Pioneer Square lies the remains of another city. After the Great Fire of 1889, local engineers elevated the street level, leaving behind the original storefronts and sidewalks in a warren of subterranean tunnels. This hidden underworld, known as the Seattle Underground, was buried to make room for progress. But it never disappeared, it just became invisible. Today, our digital infrastructure mirrors that layered reality. Security teams are tasked with safeguarding an environment built on top of earlier architectures, older assumptions, and interfaces that weren't designed for what they now support. At BSides Seattle 2025, more than a thousand practitioners came together on the Microsoft campus, in Building 92, to explore how we secure not just the software we run…  ( 7 min )

Exploring how DBSCAN uses density, not distance, to find clusters of any shape from theory and code to real-world applications like anomaly detection and geospatial mapping. Before diving into the code or real-world applications, it’s essential to understand what DBSCAN actually is and why it stands apart from traditional clustering techniques. At its core, DBSCAN short for Density-Based Spatial Clustering of Applications with Noise is a powerful algorithm that clusters data not based on shape or center points, but on the density of data points in a region. Let’s break down the key concepts that make DBSCAN unique. Density-Based Clustering : Instead of grouping points based of distance from a center(like K-MEANS). This algorithm groups points based on how crowded a region is No need for…  ( 4 min )

How I Lost 35kg and Built a Habit Tracker That Actually Works Six months ago, I was lazy, unfocused, and overwhelmed. I’d scroll mindlessly on my phone, work beyond healthy hours, skip workouts, and constantly put off things I knew were good for me. I didn’t need a fancy productivity system — I needed a push. Something simple. Visual. Relentless. That’s when I built Days Without – Habit Tracker. I wasn’t aiming to reinvent productivity apps. I built Days Without for myself — because I genuinely needed help. I was tired of breaking promises to myself like “I’ll start tomorrow” or “just 10 more minutes on Instagram.” I needed a streak counter. A clear, visual reminder of how long I’ve stuck to something. Something lightweight and shame-free, but still motivating. With Days Without, I start…  ( 4 min )

📝 What is BDD? Behavior-Driven Development (BDD) is a software development methodology that evolved from Test-Driven Development (TDD). Unlike traditional development approaches that focus on implementation details, BDD focuses on the behavior of the system from the user’s perspective. BDD encourages collaboration between developers, QA, and non-technical stakeholders through a shared language that everyone can understand. This approach bridges the gap between technical and business teams by using natural language descriptions of requirements that can also serve as tests.

When developers encounter the issue of the Samsung system UI displaying over their Flutter app on devices like the Samsung S24 Ultra, it raises important questions about compatibility and layout handling. This specific issue seems to arise post-update to One UI 7.0 and Android 15, leaving many users wondering why their app layout is affected, especially if it was functioning well before the update. Understanding the Problem The main cause of this issue appears to be related to how the new system UI interacts with Flutter’s rendering mechanism. With the update to One UI 7.0, some changes might have impacted how safe areas and overlays are managed. The SafeArea widget is designed to prevent UI elements from overlapping with system UI elements such as the status bar and navigation bar. Howeve…  ( 4 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities This project tries to make technology accessible to many more people. Today, a lot of developers are good in programming & technology but not many are proficient in English. This becomes a barrier for them to use technology. Using Amazon Q Developer, I have demonstrated a simple use of Amazon Q to generate documentation in regional languages like Hindi. Having documentation in familiar, non-English, local languages will make technology accessible to many more people, thus becoming more inclusive. Adoption of Amazon Q will also increase. https://drive.google.com/file/d/1zXTwx5VzkeTugUMlDAibUfVV4MLsWdkw/view?usp=sharing https://github.com/msr2610/neometroapi Here is how I used Amazon Q Developer: Open new chat in Amazon Q Developer Give a new "/dev" command and provide following prompt: a) From Java code file (Neocontroller.java), pick up all routes After this, Amazon Q Developer correctly generates a markdown file with description for each route in Hindi.

If your inspections rely on physical tools, tracking them doesn’t need to be manual or messy. This video walks you through how to set up, assign, and record tool usage using the Quality Inspector for Business Central. See how to define physical tools or specific items in your system with serial numbers. You can also link tools to Business Central records like fixed assets, items, or resources, and even mark some tools as “required” so inspectors must enter a serial number during testing. Learn how to assign physical tools to individual test steps within your inspection templates. This session shows how to open a checklist, pick a test, and select the tools for that specific measurement. Required tools get flagged if left blank, so nothing gets missed during the inspection process. See how users can mark tools as used, enter serial numbers (especially for required tools), and get visual feedback—like red highlights when a tool ID is missing, helping maintain traceability and compliance.

In C++, template programming allows for great flexibility by enabling developers to write generic and reusable code. One common requirement is the need to specify default template parameters when using template templates. If you have a function that utilizes a template template parameter, you may want to provide default types for those parameters, particularly when dealing with standard containers like std::unordered_map. Understanding Template Template Parameters Before we dive into the solution, let’s clarify what template template parameters are. A template template parameter is a template that takes other templates as parameters. For example, when you declare template typename Map>, you are saying that Map itself is a template that accepts two type pa…  ( 4 min )

When working with binary trees, it's common to process each node with post-order traversal (left → right → root). But when the goal is to find the maximum sum of any path, including those that may start and end at any node, we need a careful approach to handle different types of path combinations. The main idea is to use depth-first search (DFS) and, at each node, calculate: The best path that can be used to extend to the parent (choose either left or right subtree). The best complete path that can split at the current node (includes both left and right subtrees). We track a global variable res to store the maximum sum seen so far. Here’s the breakdown: For each node, recursively calculate the maximum sum path from the left and right subtrees. If a child path gives a negative sum, ignore i…  ( 8 min )

TL;DR: Bungie’s bid to toss out a Destiny 2 copyright lawsuit got shot down by the Eastern District of Louisiana. The dispute centers on two “vaulted” campaigns—The Red War and Curse of Osiris—that plaintiff Matthew Kelsey Martineau says lifted key character and faction details from his 2013–14 WordPress posts. Bungie tried to use gameplay videos, wiki pages and an affidavit (since the original code no longer runs) as “accurate reproductions,” but the court refused to treat third-party materials as a substitute for side-by-side comparison. With no way to show the vault-deleted content, the motion to dismiss was denied and Martineau’s infringement claims move forward.  ( 3 min )

Method binding refers to ensuring that this inside the method always points to the correct class instance, especially when the method is passed as a callback. setInterval @Injectable() export class MyService { private count = 0; increment() { this.count++; console.log('Count:', this.count); } start() { setInterval(this.increment, 1000); // 'this' is undefined here } } In this example, this.increment lo…  ( 3 min )

TL;DR: A Drexel University study dug into data from Portland, Oregon—tracking over 36,000 trees planted between 1990–2020—and found that mothers living within 100 meters of newly planted trees tend to have heavier, healthier babies. After controlling for factors like income, education and BMI, researchers saw each new tree bump birthweight by about 2.3 grams; hanging out near ten or more trees equated to a roughly 50-gram gain, plus lower risks of pre-term and small-for-gestational-age births. What’s cool is that this goes beyond just big old parks: even new saplings make a difference, hinting that planting trees is a simple, low-cost public-health win. Established trees also helped buffer road-density effects (think less noise and pollution), and the team thinks part of the benefit comes from the stress-busting “soft fascination” of green surroundings. The authors call for randomized trials, but treating tree-planting as a natural experiment already makes a strong case that more greenery = healthier starts to life.  ( 3 min )

In functional programming, recursion is a fundamental concept often utilized to solve various problems. This leads us to the discussion of Tail Call Optimization (TCO). This optimization allows a function to call another function, or itself, without requiring a new stack frame, effectively reducing overhead and memory usage. While many functional languages utilize TCO to enhance performance, it raises an important question: does Ruby implement tail call optimization? Understanding Tail Call Optimization (TCO) TCO is key in functional programming for several reasons. When a function calls another or itself as its last action, traditional languages allocate a new stack frame for each call, which can lead to stack overflow or excessive memory use. TCO allows the programming language to reuse …  ( 4 min )

It was one of those late-night coding marathons. for loop, something felt... heavy. squares = [] for _ in range(10): squares.append(_ * _) Wait... I wasn’t even using the variable for anything besides its own value. 👀 The Realization squares = [ _ * _ for _ in range(10) ] That’s it? That’s legal? .append(). No unnecessary scaffolding. ✅ Cleaner 🧐 Why it works: Want to filter as well? evens = [ _ for _ in range(20) if _ % 2 == 0 ] Compare that to the old-fashioned way, and it’s no contest. 🚫 Never Again... for loops for simple list building. ✨ Moral of the Story: What would a list comprehension do? 😎 🔗 Curious about using _ in Python loops? http://bhuvaneshm.in/dev-post/2  ( 3 min )

The IT industry changes faster than any other industry, due to the flexibility of how information is exchanged and processed. And so do the languages, with which programmers express their intentions to a computer. But it is my impression, that the development in this space becomes more and more like searching for a local minimum, in a space constrained by previously adopted abstractions, and the limitations that come from them. There is nothing wrong with that, but what interests me is - can we have revolutionary progress, instead of evolutionary? If it is possible, it would take questioning the assumptions made until this point, challenging our very viewpoint. So, let us engage in some critical thinking.

Servicehost.exe on Windows 11 : To fully understand how servicehost.exe works, we should know the DLL mechanism. DLL, the short form of Dynamic Link Library, is a file that contains code , data , resources , etc. that programs and services use on Windows 11. However, a DLL cannot run by itself. That’s where svchost.exe comes into the picture. The DLL file must be loaded by an executable file like svchost.exe. Windows Services written as DLLs rely on servicehost.exe to launch and manage them in memory. How are DLL and Servicehost.exe connected? On Windows 11, svchost.exe groups services effectively for better output Instead of running every program and service separately, svchost.exe groups related processes to conserve memory and reduce the system load on the Windows process.

Building JavaFactory Plugin: Can Code Generation Be Automated with LLMs? With GPT-4o, more cognitively shallow tasks are becoming candidates for automation. In particular, repetitive coding patterns — where inputs and rules are well-defined — can be partially handled by LLMs. Code generation isn't fully autonomous yet. But when interfaces and data specs are clearly described, it becomes possible to automate part of the implementation and testing process using structured prompts. This doesn’t eliminate the need for human judgment. But even if only a predictable subset of code( about 50% of code ) can be automated, the potential productivity gain is worth exploring. JavaFactory is an IntelliJ plugin built to test this idea. With a right-click in your IDE, it generates implementations, …  ( 4 min )

JavaScript (JS) started in browsers with Netscape, but its flexibility has spread it to servers (Node.js, Deno, Bun), mobile apps (React Native, Ionic), and desktop apps (Electron). Each environment needs a setup to run JS code and convert it to machine instructions. This setup is the JavaScript Runtime Environment. Here, we’ll explore what it is and its core components, preparing for a deeper look at JS execution in future articles. A runtime environment is the system that lets JavaScript code run and interact with its platform. It centers on a JavaScript engine, which parses, compiles, and executes code, turning JS into bytecode or machine code, often via Just-In-Time (JIT) compilation (more on that later!). But the engine isn’t enough. JS is single-threaded, handling one task at a time.…  ( 4 min )

The Current Landscape 🌐 The traditional inference model, pioneered by companies like OpenAI, revolves around providers offering one or a few large language models (LLMs) with 100% uptime and swift responses. This approach simplifies GPU management since all users share the same LLM, ensuring even load distribution. However, this convenience comes at a cost: Users are typically charged based on arbitrary, non-transparent metrics like token count. The selection of LLMs is sparse, they are usually censored and your data is being trained on. 😕 An alternative is the serverless model, where you rent a GPU instance and install any LLM you want with specialization and features tailored to your needs. This approach offers: Transparency: Pay only for actual GPU usage. Flexibility: Choose from th…  ( 4 min )

In the early days of IT, we manually configured servers–each one a precious snowflake, lovingly maintained and documented. But the size of the infrastructure grew and this approach couldn't scale. Chef and Puppet popularized the idea of Infrastructure-as-Code: engineers would define the state of the machine(s) in text files, stored in Git–hence the name. A global node would read these files to create a registry. Then, a local agent on each machine would check the desired state at regular intervals, and reconcile the current state with the registry. The first generation of IaC managed the state of existing machines but assumed the machine was already there. The migration to the Cloud created another issue: how do you create the machine in the first place? Another IaC tool appeared in the fo…  ( 7 min )

What Is a Shadow API? A shadow API is an application programming interface that is created or used without explicit approval from the organization’s IT or security teams. Shadow APIs can emerge from various sources, including developers experimenting with new features, legacy systems that are no longer officially supported but still in use, or services integrated outside of formal IT channels. This is part of a series of articles about API security Unlike official APIs, shadow APIs lack oversight and governance, making them invisible to the security measures typically applied to known and documented APIs. They operate under the radar of standard security and monitoring practices. Because these APIs were not introduced through sanctioned processes, they are excluded from inventory or documentation efforts. As a result, shadow APIs present significant risks. They are not subjected to regular security assessments, patches, and compliance checks that would normally be part of an API’s lifecycle management in a secure software development environment.

Let’s see how you can create a completely responsive layout using MUI Grid, step by step, with code you can copy and customize. MUI's Grid is based on top of CSS Flexbox, and it works on a 12-column layout system. It means you can divide your layout into sections without much stress, and control different section's behaviour on different screen sizes. Now you don't have to write separate CSS media queries all over the place. If you’re new: npx create-react-app mui-grid-demo cd mui-grid-demo npm install @mui/material @emotion/react @emotion/style…  ( 4 min )

In this article, I'll show you how to quickly create a script to encode your secret keys to base64, so you can use them for your JWT secret or anything else. First, let's see why we use this approach: Private keys and certificates may contain binary characters incompatible with certain systems (e.g., environment variables, .env files, YAML, JSON, XML). Base64 encoding turns them into secure ASCII strings compatible with virtually any transmission medium. Storage in environment variables/files Systems like Docker, Kubernetes, CI/CD (GitHub Actions, GitLab CI), and configuration tools (e.g., dotenv) handle text values ​​better. Base64 allows you to store keys/certificates directly as environment variables. PRIVATE_KEY_BASE64=LS0tLS1CRUdJTiBSU0EgUFJJVkFURSBL... REST, …  ( 5 min )

In Rust, when using GTK's DropDown widget, you may want to execute a closure to retrieve the selected index upon the selection change. A common issue developers face is accessing the selected choice directly from the ParamSpec. Let's dive into how to do this effectively. Understanding the DropDown and Connect Closure When you create a DropDown in GTK, you define the choices it contains. In your example, you have created a DropDown with two options: let choix = ["Choice 1","Choice 2"]; let drop_down2 = gtk::DropDown::from_strings(&choix); Here, choix is an array containing the two options. The DropDown will display these choices in the user interface. To respond to user interaction, you set up a closure that will be executed whenever the selected choice changes. The…  ( 4 min )

In the vast universe of software development, Visual Studio Code has emerged as a key tool—an unexpected bridge connecting worlds that once seemed incompatible. It has become a lifeline for developers coming from the GNU/Linux ecosystem, desperately seeking a way to write desktop applications, something they thought was lost in their environment. Its versatility allows for development in C#, C++, and FPC Pascal, avoiding alternatives like Lazarus, and offering a more modern and robust option. Personally, I’ve found myself using it as an alternative to Visual Studio 2022, since developing a .NET 6, 7, or 8 application on Linux is financially more viable for my business than doing so on Windows. But here’s the question: Why does Visual Studio Code feel like an orphaned and underappreciated sibling compared to Visual Studio 2022? Both serve incredible purposes. Visual Studio 2022 is the enterprise-grade powerhouse, while VS Code is the agile alternative—the gateway for many developers coming from GNU/Linux, looking to explore Windows and its tools, or simply wanting to use .NET Core on Linux. That in itself is a massive achievement, a step forward in software evolution. Because in the end, bluntly speaking, Linux is great... but if it doesn’t pay the bills, what can I do? As developers, we need to produce high-quality software using high-quality tools. That’s why Visual Studio Code becomes the logical and efficient choice—a path that allows us to keep programming in diverse environments while maintaining productivity and financial sustainability. Ultimately, VS Code isn’t just a code editor… it’s the bridge that unites worlds that once seemed irreconcilable.  ( 3 min )

之前写的后台的控制程序，我采用的都是用VC或者是C#写完之后然后采用AlwaysUp或者是nssm把自己写的后台程序再给做成一个Windows的服务程序。但后来想了想为什么不自己直接写一个Windows的服务程序呢。所以就开始了写服务程序的历程。 首先大致的说一下C#语言写一个Windwos服务程序的方法。说实话C#想写一个Windows服务程序相对的要简单的多。因为C#已经都给准备好了。就在创建项目的选择Windows服务项目就可以了。然后再添加一个服务安装的组件，改一下相关的配置，如：服务名、启动类型、启动权限或者叫启动时的用户。这些信息就可以了。在写代码的时候只要在开始的里面写上服务启动时需要做的工作，在结束里面写上服务停止时需要收尾的工作就大功告成了。 下面主要是说一下采用VC写Windows服务程序。这个我个人觉得相对来说有几个坑需要避。 第一个坑就是如果你从网上查的话都会说用VC写Windows服务程序的入口主函数是ServiceMain()这个函数。而实际并不是，实际上的程序入口还是从main()这个函数开始的。只不过在这个函数中我们不能做太多的事情，必须要尽快的调用StartServiceCtrlDispatcher()这函数来启动ServiceMain()函数。而且ServiceMain()这个函数的名字也并不一定就是这个，可以自定义。只不过你在网上查的人都会采用这个函数名而已。并非VC语言的规定或者约束。这个函数也只不过是在调用StartServiceCtrlDispatcher()函数的时候的一个参数而已叫什么名字并不重要。 第二坑就是服务状态的变换问题，只有你有ServiceMain()函数中调用了SetServiceStatus()函数来告诉Windows操作系统你的服务程序是开始启动了还时正在运行之中还是正在停止之中才可以。在这方面我从网上查了好长时间没有一个写的清楚的。我开始的时候以为这个函数没什么大用于是把相关的代码给删掉了，结果就会发生服务程序的状态无法改变。比如你在启动服务的时候没有及时的状态改成正在运行的话那么Windows的服务控制台就会一直启动这个服务直到启动超时而报错最后服务的状态就会卡在启动状态无法将服务停止或者删除。如果你能将服务状态进入到正在运行状态，但在发出停止服务的时候如果不能将服务的状修改成停止的话那么Windows也会一直停止这个服务直到停止超时而报错。而且这个服务的状态也会卡在停止的状态无法改变。 第三个坑就是在ServiceMain()函数中在用SetServiceStatus()函数把服务的状态修改成“正在运行”的状态之后必须要调用WaitForSingleObject()函数把这个服务的主线程给卡住然就是是一直等待发出服务停止的信号。所以在真正的主线程中你是无法再做其它的任何的工作的。故如果要想写好一个完整的Windwos服务程序就必须在ServiceMain()函数调用WaitForSingleObject()函数之前将你想做的事情都给加载完毕之后再调用WaitForSingleObject()函数将主线程卡住一直等待停止服务的指令。当停止服务的指令来临的时候再调用SetServiceStatus()函数把服务的状态修改成已经停止。 第四个这个不算是坑了这个算是一个常识。就是服务程序的调试问题。如果想调试Windows服务程序那么就只能采用“附加到进程”的方式。即先从Windows的服务管理器中启动服务，然后从Visual Studio的“调试”菜单中选择“附加到进程”的选项然后再选择自己程序的那个进程就可以了。 总结一下，那就是不论是VC写Windows服务程序还是C#写Windwos服务程序，都会有一个开始服务的初始化函数。而初始化函数中不能有死循环，但一般的服务程序又必须要用死循环，所以一个完整的Windwos服务程序一定是一个多线程的，在初始化的时候就启动其它的想要加载的死循环的线程。还会有一个程序的销毁函数，同样在销毁函数中也不能有无法完成的循环。最后就是Windwos服务程序的调试必须采用附加到进程的方式来进行。  ( 2 min )

In Java, an array is a data structure that stores a fixed-size, sequential collection of elements of the same data type. It is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created and remains fixed throughout its lifetime. Arrays are used to organize data efficiently and can be defined and initialized in various ways. Array - Group of similar datatypes Why do you use an array? Arrays are handy when you want to work with multiple values of the same data type. Instead of declaring individual variables for each value, you can group them together in an array, making your code more concise and easier to manage.

When working with Bash scripts, managing file paths and filenames can sometimes lead to unexpected sorting behavior. If you're trying to sort an array of complete filenames and want them sorted by just the filename while retaining the full paths, you're not alone in this challenge. In this article, we'll explore a solution that allows you to achieve exactly that. Why the Issue Occurs The confusion often arises from how the sort command works in conjunction with the full paths of files. When you try to sort by default, it considers the whole string, which includes the path. This results in sorting that does not reflect the ordering of the filenames, as seen in your request where sort outputs filenames based on their directory path rather than the filename itself. Step-by-Step Solution To ac…  ( 4 min )

When you're developing applications that interact with web services, you may encounter SSL certificate verification errors, even when things work fine in other tools like Postman. One common issue is the SSLCertVerificationError that occurs in Python when making API calls. Let's dive into why this might happen and how to resolve it. Understanding SSLCertVerificationError The SSLCertVerificationError signifies that Python's request to verify the SSL certificate of the server has failed. In your case, you're able to make HTTPS calls via Postman without any issues, while those same calls lead to an SSL error when executed through Python. This discrepancy often arises from differences in how each application handles SSL certificates. Why Is This Happening? In essence, Python, particularly with…  ( 4 min )

If you're looking to increase the width of input text fields in your React component, you're not alone. Many developers encounter similar issues when trying to style form inputs. Let’s delve into how you can achieve the desired width using CSS effectively. Why Are Input Fields Not Widening? The problem with input fields not responding to width changes usually stems from how CSS is applied to the form elements and the layout properties of their containers. By default, most input elements are inline or block styled, which can restrict the space they take up. Step-by-Step Solution to Increase Input Field Width To resolve your issue, you can apply custom CSS styles to the input fields. Here’s a guide on how to do it: 1.

Michelle Bond, the wife of former FTX Digital Markets co-CEO Ryan Salame, who faces federal campaign finance charges, is pushing for dismissal on the grounds that US prosecutors deceived her husband in a plea deal. In a May 7 filing in the US District Court for the Southern District of New York, Bond’s lawyers reiterated some of the claims Salame made in opposing his plea deal with the government, which ultimately still led to him serving time in prison. She claimed that prosecutors obtained a deal with Salame through “stealth and deception” by allegedly agreeing they would not file charges against Bond.  “Mr. Salame and Ms. Bond’s attorneys were advised that the agreement to cease investigating Ms. Bond could not be placed within the four corners of the Salame plea or other written agreem…

The US federal court for the Southern District of New York has sentenced former Celsius CEO Alex Mashinsky to 12 years in prison for fraud. Mashinsky’s legal team sought a light sentence. They highlighted his spotless record before the Celsius incident, along with his military service and willingness to plead guilty. But US prosecutors were less inclined to leniency, suggesting on April 28 that the judge deliver a 20-year sentence for his actions.

The Guiding and Establishing National Innovation for US Stablecoins of 2025 Act, known as the GENIUS Act, failed to pass cloture in the United States Senate on May 8, dealing a slight blow to cryptocurrency regulation in the country. The bill, sponsored by Senator Bill Hagerty and co-sponsored by Senators Tim Scott, Kirsten Gillibrand, Cynthia Lummis and Angela Alsobrooks, received last-minute pushback from Democrats, who took aim at the bill and raised concerns about US President Donald Trump’s cryptocurrency ventures. To address the concerns of Senate Democrats, the bill had already been amended to include stricter requirements for stablecoin issuers for further provisions for Anti-Money Laundering. The GENIUS Act was seen as a bipartisan effort to increase regulatory clarity for digital assets in the United States. The focus of the bill, stablecoins used for payments, was looked at as extending dollar dominance internationally and straying away from more controversial crypto topics. After the procedure failed, Senate Majority Leader John Thune criticized Democrats, saying, “Democrats have been accommodated every step of the way […] frankly, I just don’t get it.” This is a developing story, and further information will be added as it becomes available.

US President Donald Trump was reportedly manipulated by a lobbyist tied to Ripple Labs into announcing the XRP token would be part of his plans for a national cryptocurrency reserve. According to a May 8 Politico report, an employee of pro-Trump lobbyist Brian Ballard gave the president the text to a social media post she recommended he write announcing a US strategic crypto reserve that would include XRP, Solana (SOL), and Cardano (ADA). After he posted the message to his social media platform on March 2, Trump learned Ripple was one of Ballard’s clients, infuriating the president, who felt like he’d been used, Politico reported, citing two people familiar with the incident. “He is not welcome in anything anymore,” said Trump, referencing Ballard, according to the report.

The US Securities and Exchange Commission (SEC) is considering rule changes to let companies more freely issue tokenized securities, SEC Commissioner Hester Peirce said in a speech published on May 8. The regulator is “considering a potential exemptive order” for firms using blockchain technology to “issue, trade, and settle securities” that would release them from certain registration requirements, Peirce said in the speech. For example, decentralized exchanges (DEXs) may no longer need to register “as a broker-dealer, clearing agency, or an exchange,” Peirce said. The SEC has previously brought numerous charges against DEXs such as Uniswap for failing to register as securities exchanges. Firms should “not have to comply with inapt regulations, which, in many cases, were developed well b…

Layer 2s have been a great blockchain success story. They’ve reduced congestion on the Ethereum mainnet, driving down gas fees while preserving security. But maybe they’ve become too successful, drawing chain activity and fee income from the parent that spawned them? At least that’s what some are suggesting lately, most recently at Cornell Tech’s blockchain conference in late April. Indeed, some think Ethereum should be a little greedier, or at least fight harder for a bigger part of the revenue pie, particularly sequencing fees.  “People in the Ethereum Foundation [the nonprofit that supports the Ethereum ecosystem] will tell you that, ‘Yes, we effed up by being too ivory tower.’ I have heard that multiple times,” said David Hoffman, an owner at Bankless, during a panel discussion at the …

Former Celsius CEO Alex Mashinsky will probably be allowed to travel for his daughter’s wedding regardless of the outcome of his May 8 sentencing hearing. In a May 8 filing in the US District Court for the Southern District of New York, Judge John Koeltl approved an application for Mashinsky to travel from New York to Memphis, Tennessee, between May 26 and May 29 for his daughter’s wedding. The approval was available on the public docket on May 8, but later appeared to have been removed. Judge Koeltl will determine in a May 8 hearing whether Mashinsky serves prison time following a plea deal with prosecutors. The former Celsius CEO appeared ready to go to trial in 2024 until his lawyers lost a motion to have his charges dismissed. He pleaded guilty to commodities fraud and a fraudulent scheme to manipulate the price of the platform’s native token, CEL. Mashinsky has been free on a $40-million bond since July 2023, with travel outside certain areas requiring court approval, such as the roughly 900-mile (1,500-kilometer) distance between New York and Memphis. As of May 8, it’s unclear if he will be expected to surrender to authorities.

Opinion by Jonathan Farnell, CEO of Freedx It’s 2025, and over 560 million people worldwide are already using cryptocurrency — roughly 17 times the population of Tokyo. That’s a vibrant community, yet for every user who’s embraced it, billions more stand on the sidelines, put off by the complicated interactions and clunky interfaces of protocols, platforms, decentralized apps (DApps), and mobile applications. Why? Blockchain technology offers game-changing potential — decentralized ownership, secure trades — but let’s face it: Most people still find it intimidating, risky, and confusing. User experience (UX) might just be the deciding factor in whether cryptocurrency achieves mass adoption or remains a niche segment. Take complexity.

Bitcoin has reclaimed $98,000 for the first time in almost three months after the US Federal Reserve said it would keep interest rates the same for another month. The Fed’s decision to keep interest rates unchanged comes despite mounting pressure from US President Donald Trump, who just weeks ago threatened to fire Fed chair Jerome Powell for being “too late” in cutting rates. Fed cites higher unemployment, inflation risk Powell said on May 7 that the Federal Reserve rate-setting committee held rates in the 4.25% to 4.50% range due to the rising risks of higher unemployment and higher inflation. He added inflation has “come down a great deal but has been running above our 2% longer objective.” Powell said surveys in households and businesses showed a “sharp decline in sentiment” mainly due…

Arizona Governor Katie Hobbs has signed a bill into law allowing the US state to keep unclaimed crypto and establish a “Bitcoin Reserve Fund” that won’t use any taxpayer money or state funds. Hobbs signed House Bill 2749 into law on May 7, which allows Arizona to claim ownership of abandoned digital assets if the owner fails to respond to communications within three years. The state’s custodians can stake the crypto to earn rewards or receive airdrops, which can then be deposited into what Arizona has called a Bitcoin and Digital Asset Reserve Fund. “This law ensures Arizona doesn’t leave value sitting on the table and puts us in a position to lead the country in how we secure, manage, and ultimately benefit from abandoned digital currency,” the bill’s sponsor, Jeff Weninger, said in a May…

Binance founder and convicted felon Changpeng Zhao says that he applied for a pardon from US President Donald Trump shortly after denying reports that he was seeking one. Zhao, also known as CZ, said on a Farokh Radio podcast episode aired May 6 that he “wouldn’t mind” a pardon and that his lawyers have already filed the paperwork on his behalf “I got lawyers applying,” Zhao said, adding that he submitted the request after Bloomberg and The Wall Street Journal reported in March that he was seeking a pardon from Trump amid discussions of a business deal between the Trump family and Binance.US. Zhao denied the reports at the time, but said on the podcast that he thought “if they’re writing this article, I may as well just officially apply.” He added that Trump’s pardon of three BitMEX founde…

Static method is a method bound to class and not the object of class. To define static method we will use @staticmethod decorator. Explanation: If you want somebody not to access specific function through object you can do it by applying the @staticmethod. And do not pass 'self' because it will create connection with other attribute. But if you seen closely general_description is accessible through object and class also. So the question arises does this statement defy us. Well answer is, Yes, it does. Here is analogy: You will kept your screwdriver, hammer or nickel in toolbox, so that somebody want to access it he/she will look for toolbox. If you travel through airplane doesn't which model of airplane you travel the manual of that plane will remain same like how to tie seatbelt. Same as goes for static method you just access static method function through class not by object and it doesn't defy its meaning. OOPs concept is philosophical you follow the rule so that you can have strategy how write code effectively.  ( 3 min )

Ask any developer who’s used Rust what made the experience special. But dig a little deeper, and something else almost always comes up: Cargo. Rust’s package manager and build tool isn’t just “nice to have.” Now imagine Rust without it: No standard project layout. No dependency management. No easy testing or publishing. No cargo build, cargo test, or cargo run. Just a complex, opinionated systems language... with zero guidance or tooling. It would be a beautiful disaster—full of promise, but hard to harness. Shell is ancient, universal, and indispensable. Despite its power, shell scripting is stuck in the dark ages: Scripts are ad-hoc and fragile. Logic is duplicated everywhere. There's no clear way to structure or modularize projects. Reuse? Testing? Versioning? Almost nonexistent. It’s l…  ( 4 min )

Why splitting your codebase too early can quietly destroy your team’s velocity — and what to do instead. In a startup, your survival depends on how quickly you can iterate, ship features, and deliver value to end-users. This is where the foundational architecture of your startup plays a big role; additionally, things like your tech stack and choice of programming language directly affect your team’s velocity. The wrong architecture, especially premature microservices, can substantially hurt productivity and contribute to missed goals in delivering software. I've had this experience when working on greenfield projects for early-stage startups, where questionable decisions were made in terms of software architecture that led to half-finished services and brittle, over-engineered and broken l…  ( 14 min )

^ in Object Initializers The ^ operator (read as "from the end") has been part of C# since version 8, allowing developers to easily access elements from the end of collections: int last = myArray[^1]; // Last element However, until C# 13, you couldn’t use ^ inside object initializers. This restriction has now been lifted, giving developers more expressive and compact ways to initialize collections directly. Let’s explore how this change improves array initialization syntax and simplifies common patterns. Prior to C# 13: var countdown = new TimerRemaining(); countdown.buffer[^1] = 0; // Valid But you could not write: var countdown = new TimerRemaining { buffer = { [^1] = 0 } // ❌ Compiler error before C# 13 }; Now, this syntax is fully supported. ^ in Initializers public class…  ( 4 min )

In modern C#, method groups — collections of methods with the same name but different signatures — are frequently used in scenarios like: Passing methods as delegates LINQ projections Action, Func assignments Method references in event subscriptions C# 13+ introduces an important enhancement in how the compiler handles these method groups by optimizing the resolution of a natural type (i.e., an expected delegate type) for a method group. Let’s explore what changed, how it affects overload resolution, and what it means for you as a C# expert. A method group is a set of method overloads identified by a shared name: void Log(string message) { ... } void Log(string message, LogLevel level) { ... } Calling Log without parentheses creates a method group, which the compiler tries to match to…  ( 4 min )

Why this matters? The core essence of Computer Science at the lowest level is manipulating data through logical operations to perform calculations and every single CS related company in the world, is racing to do more of it, in a shorter amount of time. The challenge? Scale! As datasets grow linearly, the computational resources needed frequently grow exponentially or at least non-linearly. For example, many graph algorithms and machine learning operations scale as O(n²) or worse with data size. A seemingly modest 10x increase in data can suddenly demand 100x or 1000x more computation. This exponential scaling wall creates enormous technical and economic pressure on companies handling large datasets — forcing innovations in algorithms, hardware architectures, and distributed systems just…  ( 7 min )

When storing a segment of serialized data of uncertain length in a database, many people design the field as VARCHAR(2000) in the table schema.

Not long ago, “AI in SaaS” felt like a buzzword, a chatbot here, some automation there. But in 2025, it’s clear: I recently made a quick YouTube Short that summarizes this shift in just 60 seconds. But I wanted to share a bit more context with the dev.to community, because many of us are building this future. Here’s what’s really changing: AI handles what used to be the boring, manual work, form filling, task assignment, ticket tagging, report generation. Not only is it faster, but it actually lets teams focus on solving real problems. AI isn’t just reacting anymore, it’s learning. We’re seeing apps that adjust to each user: what they click, when they drop off, which features they ignore. AI then reshapes the experience in real time. Feels like magic (but it's models). Whether it’s predicting churn, forecasting demand, or recommending next steps, smart SaaS tools are becoming proactive. This gives users (and product teams) a serious advantage. At ClickIT, we’ve been working with startups and mid-size companies to integrate this kind of AI into their SaaS platforms. It’s wild how quickly things evolve once AI becomes part of your architecture, especially when the goal is to scale fast without losing control. Here’s the video I mentioned, just 60 seconds, made to spark ideas: How AI Is Revolutionizing SaaS in 2025 Are you already integrating AI into your product? If not ❌ — What’s holding you back?

Swapping variables is one of the most basic procedures that are done in programming. The first approach -and usually the most used by far- is to swap using a third variable, commonly named temporal variable. I'm sure you have seen it already. void swap(int* a, int* b) { int temp = *b *b = *a *a = temp } Yeah, that's a lot of pointers for explaining a swap. Blame C, not me 😒. Either way the process is the same in all languages: The value of variable b is stored in a temporal variable The value of variable a is stored in b The value stored in the temporal variable is moved to a I don't think it is necessary to say that the same process can be done replacing a with b and b with a But what if I told you that there's a way to swap values without using extra memory for a third vari…  ( 5 min )

Data Remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously written data to be recovered. Data remanence may make inadvertent disclosure of sensitive information possible should the storage media be released into an uncontrolled environment (e.g., thrown in the bin (trash) or lost). Various techniques have been developed to counter data remanence. These techniques are classified as clearing, purging/sanitizing, or destruction. Specific methods include overwriti…  ( 3 min )

Abstract APIs have become the lifeblood of modern digital ecosystems. Ensuring scalability, fairness, and resilience is no longer optional—it’s fundamental. Traditional rate limiting techniques offer a static shield against abuse and overload, but they can fall short when faced with dynamic, ever-shifting workloads. Inspired by the adaptive system design strategies from Alex Xu’s acclaimed System Design Interview series, this article explores a powerful, nuanced alternative: building adaptive rate limiters using AIMD (Additive Increase, Multiplicative Decrease). We delve into how AIMD works, why Redis is an ideal backend, and provide a full C# implementation to empower developers building the next generation of cloud-native APIs. Today’s APIs operate in a world where user demand and syst…  ( 5 min )

Introduction In this article, we tackle an interesting problem in Java programming regarding the management and display of duplicate values in an array. We are working with a Java program that identifies duplicate entries in a list and organizes their respective information. The goal is to improve the output format of our program, specifically how we display duplicates alongside their parents. Understanding this will not only enhance the readability of your console output but will also aid significantly in debugging issues and analyzing data patterns. Understanding the Problem The provided code iterates through a list of file contents, identifies duplicate entries, and tries to format them for display. However, the output currently only shows the original values, not the associated duplica…  ( 5 min )

📌 Overview If you've used LangChain, you already know the idea of "chaining logical steps" in LLM workflows. SynTeam Framework brings a structural alternative: a lightweight, JSON-based templating system that defines Units (roles), Tasks (execution order), and Operators (data routing) – all optimized for prompt-native environments like ChatGPT. Unlike LangChain’s Python-centric abstraction, SynTeam templates run entirely within the LLM context, allowing you to: Design execution flows without writing code Assign responsibility explicitly to each processing block Keep your logic transparent and reproducible inside the LLM session itself This post is for developers, LLM engineers, and technical architects who want structure and predictability without external libraries. A template consists…  ( 4 min )

Introduction: I've always been curious about how most of the technologies I use on a day-to-day basis work. One of the things we as programmers have to interact with daily is HTTP servers. Most of the time, we don't think much about it since HTTP has been around for a long time, and there are thousands of HTTP servers and clients, so most people don't give much thought to how these technologies work! As someone who worked on many web-based applications and built many restful APIs, I would like to think that I have a pretty good understanding of how the HTTP protocol works and how HTTP servers generally function, however, since I've always been using ready-made HTTP servers (Mostly Kesterl, IIS and Nginx) and HTTP clients (curl, postman, httpie) I felt that there's a lot that I can learn …  ( 14 min )

🚨 1. The Hidden Danger: S3 Buckets Left Public Many developers create S3 buckets using the default console settings, CLI scripts, or even automation templates (like CloudFormation or Terraform) — without fully reviewing access policies. 🎯 What could go wrong? public-read or public-write is enabled by mistake Bucket policies allow Principal: "*" Static websites are deployed with no access restrictions Files contain sensitive data: .env, backup.zip, user-data.csv Case Study A dev team created a bucket to share app logs for debugging.

Problem 1: Check for a Toeplitz Matrix Problem: You are given an n x n square matrix. Write a function is_toeplitz(matrix) that checks whether the matrix is a Toeplitz matrix. A Toeplitz matrix is one where every descending diagonal from top-left to bottom-right (↘️) contains the same elements. Consider this matrix: 6 7 8 4 6 7 1 4 6 The diagonals are: [1], [4, 4], [6, 6, 6], [7, 7], [8] All elements in each diagonal are equal — so this is a Toeplitz matrix ✅. To check if a matrix is Toeplitz: Loop through each element in the matrix (excluding the last row and column). For each element, compare it with the one diagonally down-right from it. If any of those pairs don’t match, return False. If the loop completes without mismatches, return True. from typing import List def is_toeplitz(matrix: List[List[int]]) -> bool: n = len(matrix) for i in range(n): for j in range(n): if i + 1 < n and j + 1 < n: if matrix[i][j] != matrix[i + 1][j + 1]: return False return True matrix = [ [6, 7, 8], [4, 6, 7], [1, 4, 6] ] print(is_toeplitz(matrix)) # Output: True  ( 3 min )

TL;DR: Famed AI researcher Tamay Besiroglu just launched Mechanize, a startup that vows to “fully automate all work” (at least white-collar jobs) by building data, evaluation tools and digital environments so AI agents can replace human labor. He even crunched the numbers: a potential $60 trillion-a-year market globally. The announcement sparked a firestorm—critics say it tarnishes the reputation of his non-profit lab Epoch (already dinged for cozy ties to OpenAI), and worry mass automation benefits companies at the expense of workers. Mechanize boasts heavyweight backers like Nat Friedman, Daniel Gross and Jeff Dean, but the debate rages on: is this the dawn of explosive economic growth or a fast track to a human‐work apocalypse?  ( 3 min )

O que é o Padrão Observer? O Observer é um padrão de projeto comportamental que define uma relação de dependência entre objetos, onde um objeto (o sujeito) notifica automaticamente outros objetos (os observadores) sempre que seu estado muda. Ele é muito útil quando várias partes do sistema precisam reagir a mudanças em um mesmo ponto. Esse padrão promove o desacoplamento entre quem emite o evento e quem reage a ele, permitindo que novos observadores sejam adicionados ou removidos em tempo de execução, sem alterar o sujeito. Em resumo, o Observer estabelece um mecanismo de notificação automática, garantindo que todos os interessados estejam atualizados sempre que algo importante acontece. As classes que devem reagir a mudanças se inscrevem no sujeito responsável por emitir essas mudanças. A classe principal recebe os observadores via o método addObserver(), registrando as implementações interessadas em ser notificadas. O método newStockData() executa a ação principal e, em seguida, notifica todos os observadores inscritos, permitindo que eles executem suas responsabilidades de forma independente. Assim caso surja uma demanda de adicionar uma nova açãoao newStockData, você não precisaria modificar a classe  ( 3 min )

Introduction In this tutorial, we will explore how to effectively join the AccountingEntity and PeriodEntity when using Entity Framework Core in C#. The aim is to filter AccountingEntity based on a Group parameter while ensuring the Period property is properly initialized from the Periods table. This is a common scenario when dealing with related database tables in a fixed schema situation. Understanding the Relationship We are working with two tables: periods and accounting. The primary key in the periods table is a combination of group and id, while the accounting table has periodid that corresponds to id in periods. The relationship between these tables is established by matching accounting.periodid with periods.id, although no foreign key is defined in the schema. Correcting the Entity…  ( 4 min )

I had read about regular expressions and thought of writing a blog on this. I will try to cover as much as possible. Let's start with the basic definition. A regular expression (also “regexp”, or just “reg”) consists of a pattern and optional flags. In short, it is the method of matching strings to a pattern. Two syntaxes can be used to create a regular expression. const regexp = new RegExp("pattern","flags"); OR const regexp = /pattern/; //without flags const regexp = /pattern/flags; Regex should be written within forward-slashes /..../. These slashes play the same role as quotes in strings. The main difference between the syntaxes is that when the regular expression remains constant, use a pattern with a slash for better performance, but if the regular expression is changing, or you d…  ( 4 min )

Understanding Maven Build Performance Maven build times can be affected by numerous factors, including: Dependency Management: The way dependencies are resolved and downloaded can impact build times. For example, if your project relies on a large number of external dependencies, Maven spends time fetching them. Build Lifecycle: The default build lifecycle consists …  ( 5 min )

Linear search is a simple algorithm that checks each element in a list sequentially until the target value is found or the list ends. Start from the first element. Compare each element with the target value. If found, return its index. If not found after checking all elements, return -1. package com.Example; break; } else { System.out.println("Not occur"); } } sc.close(); } } Time & Space Complexity Time Complexity: O(n) (Worst case: checks all elements). Space Complexity: O(1) (No extra space needed). When to Use Linear Search? ✔ Small datasets. Simple but inefficient for large datasets. Works on any list (sorted or unsorted). Easy to implement in Java. For faster searches, consider Binary Search (O(log n)) if the list is sorted. 🚀  ( 3 min )

If you’re using Redis in a Node.js application — especially in production — reliability isn’t optional. A bad connection strategy can lead to memory leaks, crashes, or endless retry loops. In this blog, I’ll show you how I built a resilient Redis integration in Express.js using ioredis, lazy loading, and a circuit breaker with opossum. At first, I used the classic approach: const redis = new Redis(); // 🤷‍♂️ at the top level But I quickly ran into issues: Connection errors on startup if Redis wasn’t ready. Too many retry attempts without a proper limit. No fallback strategy during Redis downtime. So, I rebuilt the entire integration with three key ideas: ✅ Lazy Loading instead of connecting at startup, I created a singleton getter that initializes Redis on first use: import Redis from "…  ( 6 min )

Functional programming has gained traction in modern development due to its ability to produce more predictable, modular, and testable code. In this post, we explore four fundamental principles: immutability, function composition, pure functions, and arrow functions. Immutability means that once a value is created, it cannot be changed. Instead of mutating data, we return new versions with the desired updates. ✅ Why is it useful? Prevents unpredictable side effects Easier debugging and testing Ideal for concurrent environments (like React or Redux) ❌ Mutable example: const user = { name: 'Alice', age: 25 }; user.age = 26; // Mutation ✅ Immutable example: const user = { name: 'Alice', age: 25 }; const updatedUser = { ...user, age: 26 }; // New copy with changes Function composition means …  ( 4 min )

For over 15 years, the smartphone has been the centre of our digital universe. It’s the screen we stare at, the tool we work on, the device we reach for instinctively. But look a little closer — and you’ll start to see the shift. We’re entering the post-smartphone era. Not with a bang, but through quiet disruption. And it’s already on your body. The Rise of the Wearable Web I wear a smartwatch that tracks my health, receives notifications, and lets me respond instantly. Samsung just launched a smart ring — one more layer of ambient computing wrapped around our daily lives. And of course, I can speak to an AI assistant and get intelligent, contextual responses without touching a screen. This is no longer sci-fi — this is now. A New Hub: The Invisible Puck Imagine: A tiny 5G/6G puck lives in your backpack Your glasses are your screen Your ring is your security token Your watch handles notifications and health Voice becomes your primary interface AI becomes your operating system No more swiping. No more “app folders”. No more trying to type with your thumb while walking. Screens Are Becoming Optional Even today, I can ask my glasses to play a song, call someone, or answer a question — all without touching a smartphone. I don’t need a “phone” to live connected. I just need smart inputs, wearable endpoints, and a cloud intelligence layer. What This Means App developers will have to rethink interaction: conversational, contextual, multi-device. Privacy, identity, and edge computing will take centre stage — because the phone as a walled garden will be gone. We’ll be more present — or at least, less distracted by rectangles. The Debate Begins Will we embrace ambient computing — or push back against losing physical control? One thing’s clear: the era of staring at your hand all day is giving way to something new. So here’s the question: Would you give up your phone if you could wear the web instead?  ( 4 min )

When working with TensorFlow.js, it's not uncommon to encounter errors related to tensor dimensions.

There is a lot of noise on "MCP (Model Context Protocol)" and as someone at the forefront of technology we have no choice but to follow it up. Often, despite the initial waryneess the AI hype drains my energy, some careful study turns out to generate useful insights. MCP is a protocol, but the majority of the protocol work is already done when OpenAI annouced tool use for ChatGPT. What matters now is the standardization process of the publisher of MCP, i.e. Anthropic (Creator of Claude models and tools). In addition to the publications, MCP offers server/client implementations for C#, Python, JavaScript - and that can speed up and streamline the development process. Whenever an experienced developers sees the tool use API (e.g. from OpenAI), they will immediately think of automatic code generation and streamline and tool definition process, and develop custom tooling to define those tools and serve those tools. MCP offers a ready-to-use (language-of-your-choice) implementation for a stated server. But here is a critical observation: does MCP has anything to do with AI/LLM at all? It's reinforcing what should have already been done: making systems reflective and accessible from an outside system. Here is a pun: it requires existing systems to be more reasonable (also see Forbes article on GEO). Traditionally, when a software is developed if the original developer doesn't expose useful APIs then power users have no obvious way of automating it, except through the more hacky GUI automation route. Now with the pressure of AI, vendors have to expose useful interface. LLM with its natural language nature makes it easiser for them to pick, compared to picking a more specific scripting language (or rest API), especially when the MCP server/client framework is stated and uses JsonRPC. Also see: Medium post on "Some Reflections on MCP".  ( 3 min )

Introduction In my journey through C++17, I stumbled upon the std::byte type and discovered some perplexing behavior that left me scratching my head. The main question is whether this behavior is intended by the C++ standards or if it's a quirk due to the compiler or operating system I am using. Understanding std::byte The std::byte type introduced in C++17 is designed to encapsulate the idea of a byte without its conventional mathematical interpretations. Unlike integers, std::byte doesn't implicitly convert to numeric types, which can lead to some interesting outcomes when performing operations with it. In the example I encountered, I defined a std::byte variable and used std::to_integer to convert it to different integer types. The Code Example Here’s the code snippet that raised my que…  ( 5 min )

The most visible layer is that of Artifacts. These are the tangible, observable elements of your team's culture – the tip of the iceberg, so to speak. In a DevOps context, this includes the tools they use, like CI/CD systems such as Jenkins or GitLab CI, monitoring dashboards like Grafana, and communication platforms like Slack. It also encompasses their established processes and rituals, such as daily stand-ups, sprint planning meetings, retrospectives, blameless pos…  ( 4 min )

Introduction Are you looking to enhance your AM Charts 4 bar chart with stacked columns? In this guide, I'll walk you through adding a series of stacked bars behind existing line and column series to make your data visualization more effective. Creating stacked bars can be tricky, especially with the requirements of filling the entire width of the chart. Let's dive into the issue and provide a comprehensive solution. Understanding the Problem Before we start coding, let’s discuss the challenges: the new stacked bars may all be overlapping each other, and they don't seem to fill the chart width as intended. This can result from how your series and data properties are set. Why Stacked Bars Overlap In AM Charts 4, when you configure multiple series as stacked and clustered set to false, they …  ( 5 min )

Honestly, every day feels pretty much the same now—the only difference is that on workdays, I’m tied to a schedule and have to constantly keep an eye on messages from my computer. Lately, I’ve been thinking a lot about the slow progress I’ve been making. Realistically, work takes up so much time that I barely have any quiet moments to really focus on learning. But I also can’t just give up on my current job. The only thing I can think of doing: Even if it’s not directly related to a career change, I’ll try to treat my work as a learning opportunity. Slow down, don’t just rush to complete tasks—try to gain experience from each one and reflect on it. Then, use that time to turn it into something tangible and meaningful. Feeling unusually exhausted today—going to head to bed early. Good night!  ( 3 min )

Releasing a closed-source, reusable JavaScript/TypeScript package for internal use across frontend and backend is a common challenge, especially when you want to automate it, keep things modular, and avoid unnecessary leakage of code. Here’s how I do it, step by step, using only what’s needed for a stable, repeatable workflow. Why GitHub Packages (and Not npmjs.org)? Most teams reach for npmjs.org by default, but if your utilities are strictly internal - or have some private contract processing logic you’re not ready to open-source - GitHub’s own registry is more than enough: Integrated with your repository: No extra accounts or keys to manage. Scoped access: Control exactly who gets your code. Familiar workflows: Your team’s already on GitHub; why hop away? I've used this for smart cont…  ( 4 min )

Ever wondered what keeps your online experience smooth, secure, and sometimes even anonymous? Meet the HTTP proxy — a powerful intermediary that stands between your device and the internet. At its core, an HTTP proxy processes and forwards your HTTP requests, essentially acting as a gateway. Instead of your browser connecting directly to a website, the proxy server does the job on your behalf, masking your IP address and offering a range of added benefits. To really grasp what an HTTP proxy does, you need to understand its building blocks. Hypertext Transfer Protocol (HTTP) is the standard protocol for transferring data online — everything from browsing websites to interacting with web applications. While HTTP operates over TCP/IP and Google's QUIC protocol, it lacks built-in encryption. I…  ( 5 min )

When dealing with variable length arrays (VLAs) in C, a common concern arises regarding the lifetime of such arrays when a function call is made after their declaration. According to the C17 final draft document N2176, the lifetime of an object, including a VLA, extends from its declaration until the program execution leaves the scope of that declaration. This statement often leads to questions about whether calling a function immediately after declaring a VLA results in ending its lifetime. To clarify, let's first understand what a variable length array is and its properties. A VLA is a type of array in C where the size is determined at runtime rather than at compile-time. This feature makes VLAs quite flexible for situations where the size of data is not known until the program runs. Und…  ( 5 min )

I am not new to rust. I have dabbled in axum, tonic, bevy and ratatui for some personal and work projects as well. Even then when someone asked me to write a Binary Search Tree(BST) in rust, I got scared. I didn't express this at the time but it kept bugging me inside. Anyway later on whenever I used to get time I used to ask AI tools to help me teach rust and write a BST specifically. I used Gemini and ChatGPT and both gave solutions as well. I could understand their code but still couldn't understand how they got there. They used Rc, RefCell etc. which I understand theoretically but never understood when and how to use it properly. After I didn't feel satisfied using AI answers I thought let me just read code. Rust actually provides a BST in standard library, you can find it here. Its ve…  ( 5 min )

This tutorial was originally published on IBM Developer by Markus Eisele Quarkus is a Kubernetes-native Java stack tailored for GraalVM and OpenJDK HotSpot. Quarkus offers incredibly fast boot times, low RSS memory consumption, and a fantastic developer experience with features like live coding. This quick start guide gets you up and running with Quarkus on macOS, including necessary tools. You will build a basic database application using Quarkus, Java 17, PostgreSQL, and Hibernate ORM Panache. While Hibernate ORM is the standard, powerful Jakarta Persistence implementation capable of complex mappings, it doesn't always make the most common tasks trivial. Hibernate ORM with Panache is Quarkus's solution to this, focusing specifically on making your data entities and repositories simple, straightforward, and fun to write by reducing boilerplate code for common persistence operations. We'll use standard macOS tools and package managers where possible. These are the essential tools you'll need to complete this tutorial: - Podman - SDKMAN - Java 17 - Quarkus CLI - Maven Optionally, you can also install a code editor. Quarkus integrates seamlessly with containers, especially for development services like databases and other sytems. Podman is a daemonless container engine alternative to Docker. On Mac, each Podman machine is backed by a virtual machine. Once installed, the podman command can be run directly from the Unix shell in Terminal, where it remotely communicates with the podman service running in the Machine VM. It is almost transparent in usage to Docker and easy to use for development. Install Podman. Find the latest Podman release on the GitHub Release page, and download the binary for your system architecture. At the time of writing, the latest release was v5.4.1. Install either the unversal pkg installer or the arm or amd version. Continue reading on IBM Developer  ( 3 min )

AWS Lambda is a go-to service for building scalable, event-driven applications — but with great (serverless) power comes great responsibility. Here are some practical security best practices to keep your Lambda functions secure in 2025: ✅ 1. Use the Principle of Least Privilege Create dedicated IAM roles for each Lambda function. Grant only the permissions required for that function to operate. Use IAM policies with explicit allow/deny for tighter control. 🔐 2. Secure Environment Variables Instead: Use AWS Secrets Manager or SSM Parameter Store to securely manage credentials, API keys, and tokens. Access them during function runtime using IAM roles. 🌐 3. VPC Integration for Sensitive Resources Place it inside a VPC for better network isolation. Use private subnets with minimal internet exposure. Attach VPC endpoints for secure AWS service access. 📊 4. Monitor and Log Everything Amazon CloudWatch Logs for tracking function output and errors. CloudWatch Metrics to monitor: Invocation counts Duration Throttles and errors Optionally, integrate with AWS X-Ray for tracing. 📦 5. Enable Versioning and Aliases Use Lambda versioning to avoid overwriting stable code. Use aliases (like dev, prod) to route traffic between versions easily.

In this post I want to briefly describe the usage of Isomorphic-validation, a javascript validation library that was intended to be used on the client and server side and make the process of validating user input seamless across your application. In the two previous posts I covered some aspects of using this library on the client side by creating a sign-in and sign-up form: Part 1 Part 2 Here I will show why this library is actually isomorphic. I'm going to incorporate that sign-in and sign-up examples into a simple Node.js application. If you want to run this project locally it is there: View on Github 0.

Another note app? In the past we've looked at, and used, Obsidian and Joplin. While both are great note-taking apps I'd been looking for one that had a responsive webui and possibly the ability to use a local LLM like Ollama or Exo. Blinko is a little like a callback to Mem but self-hosted and able to use local LLM's, adding a level of control over your data. This guide will be a quick setup using Docker, with a few tweaks to avoid a few headaches in getting things working with Ollama(or any AI). While there is an install.sh script that works, I tend to prefer having a docker-compose.yml file with a few tweaks to bolster security. Below are the contents of that docker-compose.yml file. Note the lines that have changeme in them, these need to be unique. For those who don't already have a …  ( 5 min )

For decades, the promise – and the anxiety – surrounding artificial intelligence has centered on automation. A future where machines handle the mundane, freeing humanity for higher pursuits. But a quiet revolution is underway. The most insightful minds in AI are now arguing that how we build and deploy AI is far more critical than what it can do. The next wave isn’t about replacing us; it’s about amplifying the uniquely human qualities of reasoning, ethical judgment, and contextual understanding – a conscious partnership designed for symbiotic outcomes. This isn’t simply a technical challenge; it’s a fundamental re-evaluation of our relationship with intelligence itself. The early narrative of AI was dominated by efficiency. Faster data processing, more accurate predictions, lower costs. T…  ( 7 min )

How many times have you seen someone build a beautiful MVP with all the cloud bells and whistles… only for it to flop? The product had everything. Lambda functions are buzzing. API Gateway routes are neatly mapped out. Cognito user pools are locked down. Files in S3, served globally via CloudFront. Data in DynamoDB. Logs in CloudWatch. IAM policies are crafted like a government document. The architecture diagram looked like a subway map during rush hour. And yet, no one used it. Zero traffic. Zero users. Zero impact. The hard truth? You don’t need AWS to build something users love. There’s a subtle poison running through the modern indie dev and startup ecosystem: overengineering. It usually starts innocently.

A Complete Understanding of Basis Path Testing We have repeatedly emphasized the importance and necessity of software testing during development and real-life runtime cycles. Path testing, a key process in the testing procedure, is often used in designing test cases. It is a structural testing technique that uses the program’s source code to identify every possible executable path. This helps detect errors and bugs along defined program routes. In this article, we will explore a specific approach to path testing known as the Basis Path Test and its nuances. Basis path testing often referred to as structured testing, is a white box testing method (testing the software’s internal programming, structure, etc.) used to design test cases. It is performed based on the control-flow graph or log…  ( 5 min )

AI has been getting a lot of attention lately—and yeah, some of the buzz is overhyped, but there’s also something real going on. From my own experience as an engineering manager, I’ve seen how AI can free up time, speed up prototyping, and help devs focus more on what they actually enjoy doing—solving problems, shipping great products, learning new stuff. I get that some people are worried AI will take their jobs. Honestly, I don’t think that’s the right question. It’s less about “Will AI replace me?” and more about “How can I use AI to level up and stay ahead?” Here are five ways I’ve seen AI help software engineers do just that.

Testing is a big part of Perl culture, so a skeleton module usually comes with a t/ directory to hold your tests.

As a softwar developer, choosing the right language and tools can make a huge difference in how efficiently you build, maintain, and scale applications. While Node.js is widely adopted in the backend world, I personally prefer Go (Golang) for several key reasons. Here's why. Go is a compiled language with built-in support for concurrency through goroutines and channels. Whether it's handling multiple HTTP requests or processing data-heavy tasks, Go offers consistent and high performance with minimal memory overhead. Its lightweight concurrency model is often simpler and more efficient than JavaScript’s event loop and async/await system. Go is statically typed, which helps catch errors early during compilation. In my experience, this leads to more robust code and reduces the kind of silent …  ( 4 min )

How We Built Delta Executor: Mobile-First Roblox Script Execution Roblox's scripting ecosystem has exploded in recent years — and so has the need for tools that empower developers to understand, test, and interact with Lua-based environments. At DeltaDevs, we created Delta Executor, a performance-first, cross-platform executor tailored for Roblox scripts on Android and iOS. Many tools in the Roblox ecosystem are outdated, unsupported, or overly complex for mobile users. Delta Executor solves that with: Script execution that’s stable across devices A secure framework with memory-safe design Keyless access for paid users (and fair key-based access for free users) Smooth compatibility across Android, iOS, and emulators for PC We built it from the ground up to handle the latest anti-cheat systems Roblox introduced in 2025. Here’s how we bypassed them. -- Delta Executor Example print("Hello from Delta Executor on Mobile!") You can load, run, and debug scripts just like this on mobile devices using our tool. Full support for popular script libraries and obfuscation is built in. While built for mobile-first use, Delta Executor also runs on Windows using emulators like BlueStacks or LDPlayer. Want to see how it works? Visit our Executor Overview Page. We're also opening up SDK access for vetted contributors and curious reverse engineers. Apply at deltadevs.net/developers We built Delta Executor with security transparency at the core. If you've seen antivirus warnings, you're not alone — many executors trigger false positives. Here's why. Official Website FAQs Script Submission Fix Guide: Executor Not Opening Delta Executor is more than an exploit tool — it’s a research sandbox for scripters, hobbyists, and curious minds working within the Roblox engine. We hope this adds value to others building tools around Lua, mobile execution environments, and anti-cheat resistance. Got thoughts? Drop your feedback or reach us via our Discord.  ( 3 min )

In tech, we’re wired for growth—more velocity, more releases, more impact, more headcount. But lately, I’ve been asking myself: Where does it stop? I’ve led high-performing teams, shipped at scale, climbed the ladder. But with each new role, I noticed a pattern—what looked like “success” on paper often came with hidden trade-offs: less time with family, more stress, fewer pauses to reflect. We’re told to aim for the next title, the bigger compensation package, the unicorn IPO—as if each step up will quiet the internal noise. But it doesn’t. Even at the top, many feel like they’re still chasing something just out of reach. And here’s the kicker: when wealth and power concentrate, whether in tech or society, others get squeezed. I’ve seen brilliant engineers burn out, not because they weren’t good enough—but because the system kept telling them they had to want more. But what if the real clarity doesn’t come from achieving more—but from needing less? Less chaos. I’ve found meaning in simpler things—mentoring a junior dev, walking outside between meetings, unplugging for dinner with my kids. These aren’t productivity hacks. They’re sanity savers. Because underneath the frameworks and sprint goals, we’re just part of something bigger—organic, changing, deeply human. The atoms in our bodies? They were once stars. Literally. We are nature. And like nature, we’re not meant to scale infinitely. So here’s a quiet question I’m sitting with—and maybe you should, too: 🔍 Is your pursuit of “more” giving you peace—or quietly taking it away?  ( 3 min )

📍 Problem description You have two applications: App 1 → deployed on Server A, port 80 App 2 → deployed on Server B, port 80 When you try to configure both behind SafeLine WAF, you get the error: Duplicate applications detected on port 80: * The reason for this error is: SafeLine allows only one listener on port 80 on the frontend. ⸻ ✅ How to solve it Since SafeLine currently does not support path-based routing, the only supported solution is domain-based routing. ⸻ Use different domain names (recommended) For example: App 1 → app1.example.com → Server A:80 App 2 → app2.example.com → Server B:80 In SafeLine: Configure one listener on port 80 Set routing rules based on the Host header (domain name) to forward traffic to the correct backend server. This way, SafeLine knows exactly which application the request is meant for. ⸻ ⚠️ Why you can’t use multiple port 80 listeners or path-based routing SafeLine can only bind to port 80 once on the frontend. Multiple port 80 listeners will always result in a duplicate port error. Path-based routing (/app1, /app2) is currently not supported in SafeLine. ⸻ 🚀 Summary recommendation ✅ Use different domain names and set up Host-based routing in SafeLine. ⸻ SafeLine Website: https://ly.safepoint.cloud/ShZAy9x https://github.com/chaitin/SafeLine https://discord.gg/dy3JT7dkmY  ( 3 min )

There is a 2-layer JSON string with multiple dynamic key values in the lower layer, excluding set/array types. {"Games": {"key1": "value1", "key2": value2,"key3":value3}} Now we need to transform the lower layer into a set of multiple layers. {"Games":{"AllGames":[{"key1":["value1"]},{"key2":["value2"]},{"key3":["value3"]}]}} SQL itself does not support multi-layer data, making it more difficult to express multi-layer sets, and the indirectly implemented code is very complex. SPL naturally supports multi-layer data and multi-layer sets: Try.DEMO A2: Take the lower-layer data (one record), change the type to a set of records, and then transpose it to a two-layer sequence.

Welcome to the final part of our SafeLine WAF series! So far, you have set up SafeLine and configured it for your environment. Now, it’s time to test your protection, finalize your Docker installation if necessary, and troubleshoot any issues that may arise. This will help you maintain a robust and reliable WAF deployment. You can test the protection effectiveness either manually or automatically. Access your website using the parameters configured in SafeLine WAF: Open your browser and visit: http://: / The default protocol is HTTP; check the SSL option to use HTTPS. The hostname can be either the SafeLine IP or your website domain (make sure the domain resolves to SafeLine). The port is the one you configured in SafeLine for the site. If your website is not accessible, please refer to the Configuration Issues section. Try these URLs to simulate attacks and confirm SafeLine blocks them: SQL Injection: http://: /?id=1%20AND%201=1 XSS Attack: http://: /?html=alert(1) If SafeLine blocks these, you’ll see the attack prevented in your browser and logged in the dashboard. ✅ sudo yum update If you get errors like “Could not resolve host” or mirrorlist failures, add Alibaba Cloud repo: curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo sudo yum install -y yum-utils sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo sudo yum -y install docker-ce docker-ce-cli containerd.io sudo systemctl start docker If you get x509 certificate errors when pulling images, it’s likely a system time or certificate issue.

Now that we've confirmed Docker is installed and running (Part 1), let's test the setup by running a simple container. This will verify that Docker can successfully download images and run containers. The Hello World Container Docker offers a lightweight "hello-world" image specifically designed to test Docker installations. This minimal container confirms that: • The Docker client can connect to the Docker daemon. 1.Let's run this test container with the following command: docker run hello-world • Check if the hello-world image exists locally This message confirms that your Docker installation is working correctly. After running the hello-world container, let's check the list of containers on your system. The container we just ran has already exited, but we can still see it in the list of all containers. 2.To see all containers (including stopped ones), run: docker ps -a The -a flag shows all containers, including those that have stopped. Without this flag, docker ps would only show running containers. STATUS column shows "Exited (0)", which means the container completed its task and exited with a status code of 0 (indicating success). The hello-world image was downloaded to your local machine. Let's verify this by listing all Docker images: docker images This confirms that the hello-world image is stored locally on your system.

The world of online dating has changed dramatically in the past few years — and artificial intelligence (AI) is playing a major role in that transformation. One emerging trend is AI dating pictures: profile photos generated or enhanced by AI to help users present their “best selves” on dating apps like Tinder, Bumble, Hinge, or even social media platforms. But what exactly are AI dating pictures, and are they a good idea? Let’s break it down. ** ✅ Generated entirely by AI — using tools like AI portrait generators or avatars based on your real face. ✅** Enhanced or edited by AI** — improving lighting, removing blemishes, sharpening features, or even subtly reshaping facial features. These photos aim to make you look more appealing without the need for professional photoshoots or heavy manua…  ( 4 min )

Most services — including social networks — offer APIs that allow third-party programs or tech-savvy users to perform actions that would normally be manual and tedious, all through code. Let’s imagine I’m blocking people on BlueSky, and I want to know if another account has blocked the same people as I have. I would need to: Retrieve my own block list Retrieve the block list of the other account And for each name, check if it's present in both lists. It’s not impossible to do — at least on BlueSky, since everything is public. But it’s a massive pain. Another example: imagine I want to block everyone who liked a post (say, because it’s a post praising Kubernetes and I don’t like Kubernetes). Here’s what I’d have to do: Find the post Retrieve the list of people who liked it Block them one by…  ( 7 min )

Troubleshooting Lag and Crashes in Swift's Camera App When developing a camera app in Swift, you may encounter issues with the startRecording function, such as lagging or crashing. These problems can result from various factors related to resource management, threading, and memory.

From time to time, it's necessary to bring all dependencies up to date. Most of them update easily. Paraglide.js? Definitely not. This post is not just a dry migration guide — it’s also about the headaches, surprises, and a few decisions you’ll have to make if you’re already deep into a SvelteKit project like I am with shrtn.io. And while we’re at it: Paraglide’s approach to minimalism still makes me smile — even if it makes the docs a bit too... minimal at times. That said, version 2.0 is a huge step forward. The documentation is better, the architecture is more maintainable, and the framework independence finally feels real. But not everything is an upgrade — especially not the developer experience when removing some of the SvelteKit-specific helpers. If you're here just for the code, fe…  ( 7 min )

As modern apps shift toward microservices and cloud-native architectures, containers have become the standard for packaging and deploying software. However, running containers in production requires more than just building images—it demands scalable orchestration and intelligent management. This blog introduces container images.

In today's fast-paced tech world, speed matters. But quality matters even more. No one wants to launch a product full of bugs or deliver a user experience that doesn't live up to expectations. That's where quality assurance (QA) comes in - not as a final check, but as an ongoing, strategic process that ensures everything runs smoothly from the start. One of the biggest mistakes companies make is putting off QA until later. By then, fixing issues becomes expensive and time-consuming. A robust QA process starts right from the planning stage. QA shouldn't be an island. Developers, designers, project managers, and QA engineers should work as a team. Communication is key. Clear documentation, shared expectations, and open feedback loops help avoid misunderstandings and missed bugs. You can't fix what you don't track. That's why a well-defined test plan is essential. It sets expectations, outlines goals, and defines what success looks like. Manual testing has its place, especially when it comes to exploratory testing or checking visual and UX elements. But automation is the backbone of a scalable QA process. Smoke tests Regression tests API testing Cross-browser checks Tools like Selenium, Cypress, or Playwright can help speed up the process. Don't overdo it with automation, though - maintaining flaky tests can slow down your team more than it helps. Pro tip: CI/CD integration Hook automated tests into your CI/CD pipeline. That way, every time new code is pushed out, it's tested instantly. Faster feedback = fewer issues in production.

Omit and Pick are some of the most loved utility types in TypeScript. They let you create new types by excluding or selecting specific properties from an existing type. union types, their behavior can be misleading - and in some cases, break your type expectations type Employee = { id: string name: string job_name: string } type Customer = { id: string name: string company: string } type Person = Employee | Customer ❌ Problem: Using Omit Directly type PersonWithoutId = Omit 🧨 Actual Result: type PersonWithoutId = { name: string } Only name survives. The fields job_name and company are lost. Why? not distributive over union types. It collapses the union into a common structure, then removes the property - resulting in a simplified, lossy type. ✅ Solution: DistributiveOmit We can fix this by explicitly distributing Omit across each union member: type DistributiveOmit = T extends any ? Omit : never type PersonWithoutId = DistributiveOmit ✅ Expected Result: type PersonWithoutId = | { name: string; job_name: string } | { name: string; company: string } 🧪 Same Fix for Pick type DistributivePick = T extends any ?

In the smoldering forges of Old Valyria, where data flows like wildfire and downtime is the true enemy, there sits a sovereign of steel and silicon—the MSP40. Forged in the fires of precision and armored against chaos, this managed Ethernet switch defends the Seven Realms of Industry 4.0 with the ruthlessness of Tywin Lannister and the foresight of Bran the Broken. Let us declare why this switch claims the Iron Throne of industrial IoT. Chapter 1: The Forge of Dragonstone MSP40 is no mere ironborn gadget. Tempered in the Foundries of Valyrian Steel, it wields powers unseen since the Age of Heroes: Dragonflame Resilience: Operates from -40°C to +85°C—hotter than Drogon’s breath, colder than the Night King’s touch. Why it shatters the old order: Legacy Switches: As reliable as Joffrey’s promises—crumbling under pressure. Chapter 2: The War of Five Ports The Battle of Blackwater Bay (Smart Factories): MSP40 commands robotic arms with the precision of Arya’s Needle, slashing downtime like Lannister soldiers. “Chaos isn’t a pit. It’s a 40% productivity gain,” it whispers. The Siege of Winterfell (Power Grids): Guards substations against EMP storms, steadfast as Brienne’s oath. “The North remembers… surge protection.” The Red Wedding (Traffic Systems): Halts data collisions at smart intersections, sparing cities from King’s Landing-level gridlock. “The network sends its regards.” The Words of House MSP40 Ports: 12 channels of fury—8 RJ45 knights and 4 SFP dragons. The Dragons of Innovation The Dark Threats Beyond the Wall Legacy Switches: Bloat like Robert Baratheon’s reign, guzzling budgets and sanity. The Prophecy of the Prince That Was Plugged In Epilogue: Winter is Here (And It’s Buffering) the MSP40 is to court chaos—a realm of molten slag and screaming CFOs.

The Remy-Linguini Dynamic If you haven't seen the movie, here's the gist: Remy is an incredible chef with all the know-how, but he's a rat, so no kitchen access. Linguini is a kitchen worker with full access but little cooking skill. Together, they form a symbiotic relationship: Remy hides under Linguini's hat and guides him on what tools to use and when. If a customer orders fries, Linguini might freeze, but Remy scopes out the kitchen, sees what's available, and gives step-by-step instructions: "Grab a knife and a cutting board. Now slice the potato." Then, Linguini executes the plan. Agentic systems work similarly.
